Anti-Assad protests in Baniyas, April 2011

This is the course of events of the Syrian civil war, it only includes major territorial changes and attacks and is not a timeline of every event.

Protests, civil uprising, and defections (January 2011 – July 2011)

Main article: Civil uprising phase of the Syrian Civil War

Small protests began in Syria on January 28, 2011. Mass protests erupted on 15 March in Damascus and Aleppo, and spread in the following days to more cities, while growing in size. The week of 15–21 March is considered by news media as the beginning of the Syrian uprising. On 18 March, the protests turned bloody when the Syrian government reacted with deadly violence. On 20 March in Daraa, after security forces opened fire on the protesting crowd, protesters burned the local Ba'ath Party headquarters, the town’s courthouse and a telephone company building. That day 15 demonstrators and 7 policemen were killed in Daraa. By 25 March, 90 civilians and 7 policemen had been killed in Syria. In his 30 March 2011 speech addressing the protests, Assad claimed that conspirators and foreign powers sought to topple his government.

The protesters’ demands until 7 April were predominantly democratic reforms, release of political prisoners, “freedom”, abolition of emergency law and an end to corruption. After 8 April, the emphasis in demonstration slogans gradually shifted towards the call for overthrowing the Assad government. Protests spread: on Friday 8 April, they occurred simultaneously in ten cities. By Friday 22 April protests occurred in twenty cities. On 25 April, the Syrian Army started a series of large-scale deadly military attacks on towns, using tanks, infantry carriers, and artillery, leading to hundreds of civilian deaths. By the end of May 2011, 1,000 civilians and 150 soldiers and policemen had been killed and thousands detained; among the arrested were many students, liberal activists and human rights advocates.

Significant armed rebellion against the state began on 4 June in Jisr al-Shugur, a city in Idlib Governorate near the Turkish border, after security forces on a post office roof had fired at a funeral demonstration. Protesting mourners set fire to the building, killing eight security officers, and then overran a police station, seizing weapons from it. Violence continued and escalated over the following days. Unverified reports claim that a portion of the security forces in Jisr defected after secret police and intelligence officers executed soldiers who had refused to fire on civilians. Later, more protesters in Syria took up arms, and more soldiers defected to protect protesters.

Both sides in the conflict used propaganda to promote their own righteousness and their opponents' wickedness (see Reporting, censoring and propaganda in the Syrian Civil War). By the end of July 2011, around 1,600 civilians and 500 security forces had been killed and 13,000 arrested.

On 29 July 2011, seven defecting Syrian officers formed the Free Syrian Army (FSA), composed of defected Syrian Armed Forces officers and soldiers, aiming "to bring this regime [= the Assad government] down" with united opposition forces. On 31 July, a nationwide crackdown nicknamed the "Ramadan Massacre" resulted in the death of at least 142 people and hundreds of injuries.

On 23 August, a coalition of anti-government groups was formed, the Syrian National Council. The group, based in Turkey, attempted to organize the opposition. However, the opposition, including the FSA, remained a fractious collection of political groups, longtime exiles, grass-roots organizers and armed militants, divided along ideological, ethnic or sectarian lines.

Throughout August, Syrian forces stormed major urban centres and outlying regions, and continued to attack protests. On 14 August, the Siege of Latakia continued as the Syrian Navy became involved in the military crackdown for the first time. Gunboats fired heavy machine guns at waterfront districts in Latakia, as ground troops and security agents backed by armour stormed several neighbourhoods. The Eid ul-Fitr celebrations, started in near the end of August, were muted after security forces fired on protesters gathered in Homs, Daraa, and the suburbs of Damascus.

By September 2011, organized units of Syrian rebels were engaged in an active insurgency campaign in multiple areas of Syria. A major confrontation between the FSA and the Syrian armed forces occurred in Rastan. From 27 September to 1 October, Syrian government forces, backed by tanks and helicopters, led a major offensive on the town of Al-Rastan in Homs Governorate, in order to drive out army defectors. The 2011 battle of Rastan between the government forces and the FSA was the longest and most intense action up until that time. After a week of fighting, the FSA was forced to retreat from Rastan. To avoid government forces, the leader of the FSA, Col. Riad Asaad, retreated to the Turkish side of Syrian-Turkish border. Many of the rebels fled to the nearby city of Homs.

By October, the FSA started to receive support from Turkey, who allowed the rebel army to operate its command and headquarters from the country's southern Hatay Governorate close to the Syrian border, and its field command from inside Syria. The FSA would often launch attacks into Syria's northern towns and cities, while using the Turkish side of the border as a safe zone and supply route. A year after its formation, the FSA gained control over many towns close to the Turkish border.

In October 2011, clashes between government and defected army units were being reported fairly regularly. During the first week of the month, sustained clashes were reported in Jabal al-Zawiya in the mountainous regions of Idlib Governorate. Syrian rebels captured most of Idlib city as well. In mid-October, other clashes in Idlib Governorate include the city of Binnish and the town of Hass in the governorate near the mountain range of Jabal al-Zawiya. In late October, other clashes occurred in the northwestern town of Maarrat al-Nu'man in the governorate between government forces and defected soldiers at a roadblock on the edge of the town, and near the Turkish border, where 10 security agents and a deserter were killed in a bus ambush. It was not clear if the defectors linked to these incidents were connected to the FSA.

According to defectors, in 2011 the Syrian government intentionally released imprisoned Islamic radicals and provided them with arms "in order to make itself the least bad choice for the international community."

Escalation (November 2011 – March 2012)

Syrian army checkpoint in Douma, January 2012

In early November, clashes between the FSA and security forces in Homs escalated as the siege continued. After six days of bombardment, the Syrian Army stormed the city on 8 November, leading to heavy street fighting in several neighborhoods. Resistance in Homs was significantly greater than that seen in other towns and cities, and some in opposition have referred to the city as the "Capital of the Revolution". Unlike events in Deraa and Hama, operations in Homs have thus far failed to quell the unrest.

November and December 2011 saw increasing rebel attacks, as opposition forces grew in number. In the two months, the FSA launched deadly attacks on an air force intelligence complex in the Damascus suburb of Harasta, the Ba'ath Syrian Regional Branch youth headquarters in Idlib Governorate, Syrian Regional Branch offices in Damascus, an airbase in Homs Governorate, and an intelligence building in Idlib. On 15 December, opposition fighters ambushed checkpoints and military bases around Daraa, killing 27 soldiers, in one of the largest attacks yet on security forces. The opposition suffered a major setback on 19 December, when a failed defection in Idlib governorate lead to 72 defectors killed.

Riot police in central Damascus, 16 January 2012

In January 2012, Assad began using large-scale artillery operations against the insurgency, which led to the destruction of many civilian homes due to indiscriminate shelling. By this time, daily protests had dwindled, eclipsed by the spread of armed conflict. January saw intensified clashes around the suburbs of Damascus, with the Syrian Army use of tanks and artillery becoming common. Fighting in Zabadani began on 7 January when the Syrian Army stormed the town in an attempt to rout out FSA presence. After the first phase of the battle ended with a ceasefire on 18 January, leaving the FSA in control of the town, the FSA launched an offensive into nearby Douma. Fighting in the town lasted from 21 to 30 January, before the rebels were forced to retreat as result of a government counteroffensive. Although, the Syrian Army managed to retake most of the suburbs, sporadic fighting continued. Fighting erupted in Rastan again on 29 January, when dozens of soldiers manning the town's checkpoints defected and began opening fire on troops loyal to the government. Opposition forces gained complete control of the town and surrounding suburbs on 5 February.

On 3 February, the Syrian army launched a major offensive to retake rebel-held neighborhoods. In early March, after weeks of artillery bombardments and heavy street fighting, the Syrian army eventually captured the district of Baba Amr, a major rebel stronghold. The Syrian Army also captured the district of Karm al-Zeitoun by 9 March, where activists said that government forces killed 47 women and children. By the end of March, the Syrian army retook control of half a dozen districts, leaving them in control of 70 percent of the city. By 14 March, Syrian troops successfully ousted insurgents from the city of Idlib after days of fighting. By early April, the estimated death toll of the conflict, according to activists, reached 10,000.

Ceasefire attempt (April 2012 – May 2012)

Kofi Annan was acting as UN–Arab League Joint Special Representative for Syria. His peace plan provided for a ceasefire, but even as the negotiations for it were being conducted, Syrian armed forces attacked a number of towns and villages, and summarily executed scores of people. Incommunicado detention, including of children, also continued. In April, Assad began employing attack helicopters against rebel forces.

On 12 April, both sides, the Syrian Government and rebels of the FSA entered a UN mediated ceasefire period. It was a failure, with infractions of the ceasefire by both sides resulting in several dozen casualties. Acknowledging its failure, Annan called for Iran to be "part of the solution", though the country has been excluded from the Friends of Syria initiative. The peace plan practically collapsed by early June and the UN mission was withdrawn from Syria. Annan officially resigned in frustration on 2 August 2012.

Renewed fighting (June 2012 – July 2012)

Main article: Timeline of the Syrian Civil War (May–August 2012)

Following the Houla massacre of 25 May 2012, in which 108 people were summarily executed and the consequent FSA ultimatum to the Syrian government, the ceasefire practically collapsed, as the FSA began nationwide offensives against government troops. On 1 June, President Assad vowed to crush the anti-government uprising.

On 5 June, fighting broke out in Haffa and nearby villages in the coastal governorate of Latakia Governorate. Government forces were backed by helicopter gunships in the heaviest clashes in the governorate since the revolt began. Syrian forces seized the territory following days of fighting and shelling. On 6 June 78 civilians were killed in the Al-Qubeir massacre. According to activist sources, government forces started by shelling the village before the Shabiha militia moved in. The UN observers headed to Al-Qubeir in the hope of investigating the alleged massacre, but they were met with a roadblock and small arms fire and were forced to retreat.

On 12 June 2012, the UN for the first time officially proclaimed Syria to be in a state of civil war. The conflict began moving into the two largest cities, Damascus and Aleppo. In both cities, peaceful protests – including a general strike by Damascus shopkeepers and a small strike in Aleppo were interpreted as indicating that the historical alliance between the government and the business establishment in the large cities had become weak.

On 22 June, a Turkish F-4 fighter jet was shot down by Syrian government forces, killing both pilots. Syria and Turkey disputed whether the jet had been flying in Syrian or international airspace when it was shot down. Despite Turkish Prime Minister Recep Tayyip Erdoğan's vows to retaliate harshly against Assad's government, no such intervention materialised. Bashar al-Assad publicly apologised for the incident. By 10 July, rebel forces had captured most of the city of Al-Qusayr, in Homs Governorate, after weeks of fighting. By mid-July, rebels had captured the town of Saraqeb, in Idlib Governorate.

By mid-July 2012, with fighting spread across the country and many people killed, the International Committee of the Red Cross declared the conflict a civil war. Fighting in Damascus intensified, with a major rebel push to take the city. On 18 July, Syrian Defense Minister Dawoud Rajiha, former defense minister Hasan Turkmani, and the president's brother-in-law General Assef Shawkat were killed by a suicide bomb attack in Damascus. The Syrian intelligence chief Hisham Ikhtiyar, who was injured in the same explosion, later succumbed to his wounds. Both the FSA and Liwa al-Islam claimed responsibility for the assassination.

In late July, government forces managed to break the rebel offensive on Damascus, although fighting still continued in the outskirts. After this, the focus shifted to the battle for control of Aleppo. On 25 July, multiple sources reported that the Assad government was using fighter jets to attack rebel positions in Aleppo and Damascus, and on 1 August, UN observers in Syria witnessed government fighter jets firing on rebels in Aleppo. In early August, the Syrian Army recaptured Salaheddin district, an important rebel stronghold in Aleppo. In August, the government began using fixed-wing warplanes against the rebels.

On 19 July, Iraqi officials reported that the FSA had gained control of all four border checkpoints between Syria and Iraq, increasing concerns for the safety of Iraqis trying to escape the violence in Syria. On 19 September, rebel forces seized a border crossing between Syria and Turkey in Ar-Raqqah Governorate. It was speculated that this crossing could provide opposition forces with strategic and logistical advantages.

In late September, the FSA moved its command headquarters from southern Turkey into northern Syria. On 9 October, rebel forces seized control of Maarat al-Numan, a town in Idlib governorate on the highway linking Damascus with Aleppo. By 18 October, the FSA had captured Douma, the biggest suburb of Damascus. Lakhdar Brahimi arranged for a ceasefire during Eid al-Adha in late October, but it quickly collapsed.

After Brahimi's ceasefire agreement ended on 30 October, the Syrian military expanded its aerial bombing campaign in Damascus. A bombing of the Damascus district of Jobar was the first instance of a fighter jet being used to bomb Damascus. The following day, Gen. Abdullah Mahmud al-Khalidi, a Syrian Air Force commander, was assassinated by opposition gunmen in the Damascus district of Rukn al-Din. In early November 2012, rebels made significant gains in northern Syria. The rebel capture of Saraqib in Idlib governorate, which lies on the M5 highway, further isolated Aleppo. Due to insufficient anti-aircraft weapons, rebel units attempted to nullify the government's air power by destroying landed helicopters and aircraft on air bases. On 3 November, rebels launched an attack on the Taftanaz air base.

On 18 November, rebels took control of Base 46 in the Aleppo Governorate, one of the Syrian Army's largest bases in northern Syria, after weeks of intense fighting. Defected General Mohammed Ahmed al-Faj, who commanded the assault, stated that nearly 300 Syrian troops had been killed and 60 had been captured, with rebels seizing large amounts of heavy weapons, including tanks. On 22 November, rebels captured the Mayadeen military base in the country's eastern Deir ez-Zor Governorate. Activists said this gave the rebels control of a large amount of territory east of the base, stretching to the Iraqi border. On 29 November, at approximately 10:26 UTC, the Syrian Internet and phone service was shut off for a two-day period. Syrian government sources denied responsibility and blamed the blackout on fiber optic lines near Damascus becoming exposed and damaged; Edward Snowden in August 2014 claimed that this Internet breakdown had been caused, though unintendedly, by hackers of the NSA during an operation to intercept Internet communication in Syria.

In mid-December 2012, American officials said that the Syrian military had fired Scud ballistic missiles at rebel fighters inside Syria. Reportedly, six Scud missiles were fired at the Sheikh Suleiman base north of Aleppo, which rebel forces had occupied. It is unclear whether the Scuds hit the intended target. The government denied this claim. Later that month, a further Scud attack took place near Marea, a town north of Aleppo near the Turkish border. The missile appeared to have missed its target. That same month, the British Daily Telegraph reported that the FSA had now penetrated into Latakia Governorate's coast through Turkey. In late December, rebel forces pushed further into Damascus, taking control of the adjoining Yarmouk and Palestine refugee camps, pushing out pro-government Popular Front for the Liberation of Palestine-General Command fighters with the help of other factions. Rebel forces launched an offensive in Hama governorate, later claiming to have forced army regulars to evacuate several towns and bases, and stating that "three-quarters of western rural Hama is under our control." Rebels also captured the town of Harem near the Turkish border in Idlib governorate, after weeks of heavy fighting.

On 11 January 2013, Islamist groups, including al-Nusra Front, took full control of the Taftanaz air base in the Idlib governorate, after weeks of fighting. The air base was often used by the Syrian military to carry out helicopter raids and deliver supplies. The rebels claimed to have seized helicopters, tanks and multiple rocket launchers, before being forced to withdraw by a government counter-attack. The leader of the al-Nusra Front said the amount of weapons they took was a "game changer". On 11 February, Islamist rebels captured the town of Al-Thawrah in Ar-Raqqah Governorate and the nearby Tabqa Dam, Syria's largest dam and a key source of hydroelectricity. The next day, rebel forces took control of Jarrah air base, located 60 kilometres (37 mi) east of Aleppo. On 14 February, fighters from al-Nusra Front took control of Shadadeh, a town in Al-Hasakah Governorate near the Iraqi border.

On 20 February, a car bomb exploded in Damascus near the Ba'ath Syrian Regional Branch headquarters, killing at least 53 people and injuring more than 235. None of the groups claimed responsibility. On 21 February, the FSA in Quasar began shelling Hezbollah positions in Lebanon. Prior to this, Hezbollah had been shelling villages near Quasar from within Lebanon. A 48-hour ultimatum was issued by a FSA commander on 20 February, warning the militant group to stop the attacks.

On 2 March, intense clashes between rebels and the Syrian Army erupted in the city of Raqqa, with many reportedly killed on both sides. On the same day, Syrian troops regained several villages near Aleppo. By 3 March, rebels had overrun Raqqa's central prison, allowing them to free hundreds of prisoners, according to the SOHR. The SOHR also stated that rebel fighters were now in control of most of an Aleppo police academy in Khan al-Asal, and that over 200 rebels and government troops had been killed fighting for control of it.

By 6 March, the rebels had captured the city of Raqqa, effectively making it the first provincial capital to be lost by the Assad government. Residents of Raqqa toppled a bronze statue of his late father Hafez Assad in the centre of the city. The rebels also seized two top government officials. On 18 March, the Syrian Air Force attacked rebel positions in Lebanon for the first time. The attack occurred at the Wadi al-Khayl Valley area, near the town of Arsal. On 21 March, a suspected suicide bombing in the Iman Mosque in Mazraa district killed as many as 41 people, including the pro-Assad Sunni cleric, Sheikh Mohammed al-Buti. On 23 March, several rebel groups seized the 38th division air defense base in southern Daraa governorate near a highway linking Damascus to Jordan. On the next day, rebels captured a 25 km strip of land near the Jordanian border, which included the towns of Muzrib, Abdin, and the al-Rai military checkpoint.

On 25 March, rebels launched one of their heaviest bombardments of Central Damascus since the revolt began. Mortars reached Umayyad Square, where the Ba'ath Party headquarters, Air Force Intelligence and state television are located. On 26 March, near the Syrian town of al-Qusayr, rebel commander Khaled al Hamad, who commands the Al Farooq al-Mustakilla Brigade and is also known by his nom de guerre Abu Sakkar, ate the heart and liver of a dead soldier and said "I swear to God, you soldiers of Bashar, you dogs, we will eat from your hearts and livers! O heroes of Bab Amr, you slaughter the Alawites and take out their hearts to eat them!" in an apparent attempt to increase sectarianism. Video of the event emerged two months later and resulted in considerable outrage, especially from Human Rights Watch which classified the incident as a war crime. According to the BBC, it was one of the most gruesome videos to emerge from the conflict to-date. On 29 March, rebels captured the town of Da'el after fierce fighting. The town is located in Daraa Governorate, along the highway connecting Damascus to Jordan. On 3 April, rebels captured a military base near the city of Daraa.

Government and Hezbollah offensives (April 2013 – June 2013)

Further information: Al-Qusayr offensive and Battle of al-Qusayr (2013)

On 17 April, government forces breached a six-month rebel blockade in Wadi al-Deif, near Idlib. Heavy fighting was reported around the town of Babuleen after government troops attempt to secure control of a main highway leading to Aleppo. The break in the siege also allowed government forces to resupply two major military bases in the region which had been relying on sporadic airdrops. On 18 April, the FSA took control of Al-Dab'a Air Base near the city of al-Qusayr. The base was being used primarily to garrison ground troops. Meanwhile, the Syrian Army re-captured the town of Abel. The SOHR said the loss of the town will hamper rebel movements between al-Qusayr and Homs city. The capture of the airport would have relieved the pressure on the rebels in the area, but their loss of Abel made the situation more complicated. The same day, rebels reportedly assassinated Ali Ballan, who was a government employee, in the Mazzeh district of Damascus. On 21 April, government forces captured the town of Jdaidet al-Fadl, near Damascus.

In April, government and Hezbollah forces launched an offensive to capture areas near al-Qusayr. On 21 April, pro-Assad forces captured the towns of Burhaniya, Saqraja and al-Radwaniya near the Lebanese border. By this point, eight villages had fallen to the government offensive in the area. On 24 April, after five weeks of fighting, government troops re-took control of the town of Otaiba, east of Damascus, which had been serving as the main arms supply route from Jordan. Meanwhile, in the north of the country, rebels took control of a position on the edge of the strategic Mennagh Military airbase, on the outskirts of Aleppo. This allowed them to enter the airbase after months of besieging it.

On 2 May, government forces captured the town of Qaysa in a push north from the city's airport. Troops also retook the Wadi al-Sayeh central district of Homs, driving a wedge between two rebel strongholds. SOHR reported a massacre of over 100 people by the Syrian army in the coastal town of Al Bayda, Baniyas. However, this could not be independently verified due to movement restrictions on the ground. Yet the multiple video images that residents said they had recorded– particularly of small children, were so shocking that even some government supporters rejected Syrian television's official version of events, that the army had simply "crushed a number of terrorists." On 3 May, the Syrian army backed by the Shabiha reportedly committed a massacre of civilians near the city of Baniyas. The Syrian Observatory for Human Rights said that at least 50 people – and possibly as many as 100 – were killed and that dozens of villagers were still missing.

On 8 May, government forces captured the town of Khirbet Ghazaleh, situated along the highway to the Jordanian border. Over 1,000 rebel fighters withdrew from the town due to the lack of reinforcements and ammunition. The loss of the town also resulted in the reopening of the government supply-route to the city of Daraa. The rebels continued to withdraw from other towns so as to not face the Army's advance along the highway. On 11 May, the rebels managed to cut a newly build desert road used as an Army supply route between central Syria and Aleppo's airport. On 12 May, government forces took control of Khirbet Ghazaleh and secured the highway near the town. By mid-May, due to the recent Army gains in retaking strategically important locations, military analysts pointed out that the government would have a major advantage in any future peace talks. Analysts on both sides credited the government advances to the restructuring of their forces, which they filled with thousands of militia irregulars trained partly by Hezbollah and Iranian advisers in counter-insurgency operations. The government's success was also credited to the shift by the Army from trying to recapture the whole country to holding on to strategic areas.

On 13 May, government forces captured the towns of Western Dumayna, Haidariyeh, and Esh al-Warwar allowing them to block supplies to the rebels in al-Qusayr. On 16 May, rebels stated that they recaptured the town of Al-Qisa. On 17 May, rebels captured four villages in Eastern Hama, including the Alawite town of Tulaysiah. The villages were abandoned by its residents before the rebels arrived. On 19 May, government forces captured the town of Halfaya in Hama governorate. The Syrian army also launched its offensive against the town of Qusayr. A military source reported that the Army entered Qusayr, capturing the city center and the municipality building. One opposition activist denied this, but another confirmed the Army was in control of 60 percent of the city. During the day's fighting, Hezbollah commander Fadi al-Jazar was killed.

An opposition source said the attack was launched from the east and the south and that Hezbollah fighters took control of the town hall within a few hours. He added that the fighting was then concentrated in the northern part of the city. The attack appeared to surprise the rebels, who expected the army to push by the north on several rebel-controlled villages before attacking the city. The turning point of the offensive was reached when Hezbollah fighters took control of the Al Tal area overlooking Qusayr. Several rebels fighters accused some commanders from fleeing the Al tal area at the last minute. Meanwhile, SOHR reported that the Syrian army was at the area by the western neighborhood of al-Quseir in order to lay siege on the city itself. On 23 May, rebels captured a military base near the town of Nairab. By 29 May, government forces captured the al-Dabaa air base, north of al-Qusayr. On 1 and 2 June, after heavy fighting, the Syrian Army recaptured three of the Alawite villages that had been previously captured by the rebels in Eastern Hama governorate. On 5 June, rebel forces withdrew fully from al-Qusayr. The following day, government forces captured the nearby village of Dabaa.

Za'atri camp for Syrian refugees in Jordan

On 6 June, rebels temporarily captured the Quneitra border crossing which links the Israeli-occupied Golan Heights with Syria. However, the same day, government forces counter-attacked with tanks and armoured personnel carriers, recapturing the crossing. On 7 June, Syrian troops backed by Hezbollah captured two villages north of al-Qusayr: Salhiyeh and Masoudiyeh. The next day, they captured the village of Buwaydah, the last rebel-held village in the al-Qusayr region. Between 7 and 14 June, Army troops, government militiamen, and Hezbollah fighters launched operations in Aleppo Governorate. Over a one-week period, government forces had advanced both in Aleppo city and the countryside around the city. However, on 14 June, according to an opposition activist, the tide had started reversing, after rebels managed to halt an armoured reinforcement column from Aleppo city for two government-held Shiite villages northwest of the city. Rebels claimed they destroyed one tank and killed 20 government soldiers northwest of the town of Maaret al-Arteek. Before the column was stopped, government forces had captured the high ground at Maaret al-Arteek, threatening rebel positions. Government forces also made some advances in the southern part of Aleppo governorate, capturing the village of Ain-Assan. During the fighting in Aleppo city itself, on 13 June, government forces managed to temporarily advance into the rebel-held Sakhour district from two directions, but were soon repelled. Some described it as possibly a probing attack and not a full assault.

On 10 June, Shia pro-government fighters from the village of Hatla, east of Deir al-Zour, attacked a nearby rebel position, killing four rebels. The next day, in retaliation for the attack, thousands of rebels attacked and captured the village, killing 60 residents, fighters and civilians, according to SOHR. 10 rebel fighters were killed during the attack. At dawn on 13 June, rebels seized an Army position on the northern edge of the town of Morek, which is located on the north-south highway, in fighting that killed six soldiers and two rebels. Later in the day, the Army shelled the base and sent reinforcements. On 14 June, the Al Nusra front captured a military barracks near Idlib city. On 15 June, the Syrian Army captured the Damascus suburb of Ahmadiyeh near the city's airport. Rebels said fighting began after rebels entered the town to use it as a position to launch mortars on the Damascus airport. They added that fighting was ongoing. On 22 June, the Syrian Army captured the rebel stronghold town of Talkalakh. Four days later, the Army captured the town of Al-Qariatayn, also in Homs governorate.

Continued fighting (July 2013 – October 2013)

On 28 June, rebel forces captured a major military checkpoint in the city of Daraa. On 12 July FSA reported that one of its commanders, Kamal Hamami, had been killed by Islamists a day before. The rebels declared that the assassination by the Islamic State of Iraq and Levant, was tantamount to a declaration of war. On 17 July, FSA forces took control of most of the southern city of Nawa after seizing up to 40 army posts stationed in the city. On 18 July, Kurdish YPG forces secured control of the northern town of Ras al-Ain, after days of fighting with the al-Nusra Front. In the following three months, continued fighting between Kurdish and mainly jihadist rebel forces led to the capture of two dozen towns and villages in Hasakah Governorate by Kurdish fighters, while the Jihadists made limited gains in Aleppo and Raqqah governorates after they turned on the Kurdish rebel group Jabhat al-Akrad over its relationship with the YPG. In Aleppo governorate, Islamists massacred the Kurds leading to a mass migration of civilians to the town of Afrin.

American jets began bombing ISIL in Syria on 23 September 2014, raising U.S. involvement in the war-torn country. At least 20 targets in and around Raqqa were hit, the opposition group Syrian Observatory for Human Rights said. Foreign partners participating in the strikes with the United States were Bahrain, Saudi Arabia, the United Arab Emirates, Qatar and Jordan. The U.S. and "partner nation forces" began striking ISIL targets using fighters, bombers and Tomahawk missiles, Pentagon spokesman Rear Adm. John Kirby said.

U.S. aircraft include B-1 bombers, F-16s, F-18s and Predator drones, with F-18s flying missions off the USS George H.W. Bush (CVN-77) in the Persian Gulf. Tomahawk missiles were fired from the destroyer USS Arleigh Burke (DDG-51) in the Red Sea. Syria's Foreign Ministry told the Associated Press that the U.S. informed Syria's envoy to the U.N. that "strikes will be launched against the terrorist group in Raqqa." The United States informed the Free Syrian Army beforehand of the impending airstrikes, and the rebels said that weapons transfers to the Free Syrian Army had begun.

The United States also attacked a specific faction of Al Nusra called the Khorasan Group, who according to the United States had training camps and plans for attacking the United States in the future.

The same day Israel shot down a Syrian warplane after it entered the Golan area from Quneitra.

Turkey also launched an official request to the UN for a no fly zone over Syria.

In the last days of October Jabhat al-Nusra, reportedly reinforced by ISIL, attacked headquarters of one of FSA units in Deir Sinbul, forcing them to flee into Zawiya mountains. Al-Nusra is believed to have captured significant amount of weapons delivered to the rebels by CIA, including anti-tank missiles.
