Renewed fighting (June–October 2012) Following the
Houla massacre of 25 May 2012, in which 108 people were summarily executed and the consequent FSA ultimatum to the Syrian Ba'athist 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. (left) and a

Conquest Brigade, part of the FSA in
Tell Rifaat, north of
Aleppo, 31 July 2012. On 5 June,
fighting broke out in Haffa and nearby villages in the coastal governorate of
Latakia Governorate. Syrian Army troops were backed by
helicopter gunships in the heaviest clashes in the governorate since the revolt began. Government 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, the Syrian Army 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 Ba'ath 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 15 July 2012, with fighting spread across the country and 16,000 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 died from his injuries. Both the FSA and Liwa al-Islam claimed responsibility for the assassination. In mid-July, rebel forces
attacked Damascus and were repelled in two weeks, although
fighting continued in the outskirts. After this, the focus shifted to the
battle for control of Aleppo. On 25 July, multiple sources reported that the 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 Ba'athist 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
Raqqa Governorate. It was speculated that this crossing could provide opposition forces with strategic and logistical advantages due to Turkish support of the rebels, whose headquarters subsequently relocated from southern Turkey into northern Syria. On 6 September 2012 Kurdish activists reported that 21 civilians were killed in the Kurdish neighborhood of Sheikh Maqsud in
Aleppo, when the Syrian Army shelled the local mosque and its surroundings. Despite the district being neutral during the
Battle of Aleppo and free of Ba'athist government and FSA clashes, local residents believed that the district was shelled as retaliation for sheltering anti-government civilians from other parts of the city. In a statement released shortly after the deaths, the Kurdish People's Protection Units (YPG) vowed to retaliate. A few days later, Kurdish forces killed 3 soldiers in
Afrin () and captured a number of other Ba'athist government soldiers in
Ayn al-Arab () and
Al-Malikiyah () from where they drove the remaining Ba'athist government security forces. It was also reported that the Ba'athist government had begun to arm Arab tribes around
Qamishli in preparation for a possible confrontation with Kurdish forces, who still did not completely control the city. At least 8 Ba'athist government soldiers were killed and 15 wounded by a car bomb in the al-Gharibi district of Qamishli on 30 September 2012. The explosion targeted the Political Security branch. In October, rebel forces
seized control of Maarat al-Numan, a town in Idlib Governorate on the highway linking Damascus with Aleppo and captured
Douma, marking increased influence in
Rif Dimashq. Lakhdar Brahimi arranged for a ceasefire during
Eid al-Adha in late October, but it quickly collapsed.
Rebel offensives (November 2012–April 2013) 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 Ba'athist 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
Mayadin 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 officials blamed the blackout on terrorists having cut "a main fiber optic cable connecting Damascus to the rest of the world";
Edward Snowden in August 2014 claimed that this Internet breakdown had been caused, though unintended, 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. 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-Ba'athist 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 Ba'athist 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
Raqqa 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 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 Ba'athist 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 al-Assad in the centre of the city. The rebels also seized two top Ba'athist 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. Fighting between the army and YPG fighters in the Kurdish village of Gir Zîro (Tall Adas), near
al-Maabadah (), where an army battalion of around 200 soldiers had been blockaded YPG forces claimed to have expelled Ba'athist government after the clashes. One soldier was reportedly killed and another eight injured, while seven were captured (later released Fighting at the oil field near Gir Zîro ended on 21 January, when Ba'athist government forces withdrew after receiving no assistance from Damascus. In Rumeilan, directly west of al-Maabadah, another 200 soldiers had been surrounded by YPG forces, and 10 soldiers were reported to have defected. heavy clashes broke out between the YPG and Ba'athist government troops in the PYD/YPG-held district Ashrafiyah where, according to SOHR, at least 3 soldiers and 5 pro-Ba'athist government militiamen were killed. The fighting followed deadly shelling on 31 January on Ashrafiyah, in which 23 According to its own reports, the YPG lost 7 of its members in the fighting, while also claiming that 48 soldiers were killed and 22 captured, and a further 70 injured. In early March, YPG forces established full control of oil fields and installations in north-east Syria after Ba'athist government forces posted there surrendered. Also, YPG assaulted Ba'athist government forces and took control of the towns of
Tall ʿAdas, which is adjacent to Rumeilan oil fields, and
Al-Qahtaniya ().
Ba'athist government offensives (April–June 2013) On 17 April, Ba'athist government forces breached a six-month rebel blockade in Wadi al-Deif, near Idlib. Heavy fighting was reported around the town of Babuleen after Ba'athist government troops attempt to secure control of a main highway leading to Aleppo. The break in the siege also allowed Ba'athist 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 would 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 Ba'athist government employee, in the Mazzeh district of Damascus. On 21 April, Ba'athist government forces
captured the town of Jdaidet al-Fadl, near Damascus. In April, Ba'athist 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 Ba'athist government offensive in the area. On 24 April, after five weeks of fighting, Ba'athist 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, Ba'athist 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 had recorded – particularly of small children, were so shocking that even some Ba'athist government supporters rejected Syrian television's official version of events, that the army had simply "crushed a number of terrorists." On 15 June, the Syrian Army captured the Damascus suburb of Ahmadiyeh near the city's airport, and on 22 June, captured the rebel stronghold town of
Talkalakh.
Continued fighting (July–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 Raqqa 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. On 22 July, FSA fighters seized control of the western Aleppo suburb of
Khan al-Asal. The town was the last Ba'athist government stronghold in the western portion of Aleppo Governorate. On 27 July, after weeks of fighting and bombardment in Homs, the Syrian Army captured the historic
Khalid ibn al-Walid Mosque, and two days later, captured the district of Khaldiyeh. On 4 August, around 10 rebel brigades, launched
a large-scale offensive on the Ba'athist government stronghold of
Latakia Governorate. Initial attacks by 2,000 opposition members seized as many as 12 villages in the mountainous area. Between 4 and 5 August 20 rebels and 32 Ba'athist government soldiers and militiamen had been killed in the clashes. Hundreds of Alawite villagers fled to Latakia. By 5 August, rebel fighters advanced to 20 kilometers from Qardaha, the home town of the Assad family. However, in mid-August, the military counter-attacked and recaptured all of the territory previously lost to the rebels in the coastal region during the offensive. A Syrian security force source "told AFP the army still had to recapture the Salma region, a strategic area along the border with Turkey." According to a
Human Rights Watch report 190 civilians were killed by rebel forces during the offensive, at least 67 being executed while fleeing, including 48 women and 11 children. Another 200 civilians, primarily women and children, were taken hostage. On 6 August, rebels captured
Menagh Military Airbase after a 10-month siege. The strategic airbase is located on the road between Aleppo city and the Turkish border. On 21 August,
a chemical attack took place in the Ghouta region of the Damascus countryside, leading to thousands of casualties and several hundred dead in the opposition-held stronghold. The attack was followed by a military offensive by Ba'athist government forces into the area, which had been hotbeds of the opposition. On 24 August, rebels captured the town of
Ariha. However, Ba'athist government forces recaptured Ariha on 3 September. On 26 August, rebel forces took over the town of
Khanasir in Aleppo Governorate which was the Ba'athist government's last supply route for the city of Aleppo. On 8 September, rebels led by the al-Nusra Front
captured the Christian town of Maaloula, 43 km north of Damascus, The Syrian Army launched a counterattack a few days later, recapturing the town. On 18 September, the
Islamic State of Iraq and the Levant (ISIS) overran the FSA-held town of Azaz in the north. The fighting was the most severe since tensions rose between militant factions in Syria earlier in the year. Soon after ISIS captured Azaz, a ceasefire was announced between the rival rebel groups. However, in early October, more fighting erupted in the town. On 20 September, Alawite militias including the NDF killed 15 civilians in the Sunni village of
Shaykh al-Hadid in Hama Governorate. The massacre occurred in retaliation for a rebel capture of the village of Jalma, in Hama, which killed five soldiers, along with the seizure of a military checkpoint which killed 16 soldiers and 10 NDF militiamen. In mid-September, the military captured the towns of Deir Salman and Shebaa on the outskirts of Damascus. The Army also captured six villages in eastern Homs. Fighting broke out in those towns again in October. On 28 September, rebels seized the Ramtha border post in
Daraa Governorate on the Syria Jordan crossing after fighting which left 26 soldiers dead along with 7 foreign rebel fighters. On 3 October, AFP reported that Syria's army re-took the town of
Khanasir, which is located on a supply route linking central Syria to the city of Aleppo. On 7 October, the Syrian Army managed to reopen the supply route between Aleppo and Khanasir. On 9 October, rebels seized the Hajanar guard post on the Jordanian border after a month of fierce fighting. Rebels were now in control of a swath of territory along the border from outside of Daraa to the edge of Golan Heights. The same day, Hezbollah and Iraqi Shiite fighters, backed up by artillery, air-strikes and tanks, captured the town of Sheikh Omar, on the southern outskirts of Damascus. Two days later, they also captured the towns of al-Thiabiya and Husseiniya on the southern approaches to Damascus. The capture of the three towns strengthened the Ba'athist government hold on major supply lines and put more pressure on rebels under siege in the Eastern Ghouta area. On 14 October, SOHR reported that rebels captured the Resefa and Sinaa districts of
Deir ez-Zor city, as well as Deir ez-Zor's military hospital.
Ba'athist Government offensives (October–December 2013) The Syrian Army along with its allies, Hezbollah and the
al-Abas brigade, launched an offensive on Damascus and Aleppo. On 16 October,
AFP reported that Syrian troops recaptured the town of Bweida, south of Damascus. On 17 October, the Syrian Ba'athist government's head of Military Intelligence in
Deir ez-Zor Governorate, Jameh Jameh, was assassinated by rebels in Deir ez-Zor city. SOHR reported that he had been shot by a rebel sniper during a battle with rebel brigades. On 24 October, the Syrian Army retook control of the town of Hatetat al-Turkman, located southeast of Damascus, along the Damascus International Airport road. On 26 October, Kurdish rebel fighters seized control of the strategic Yarubiya border crossing between Syria and Iraq from al-Nusra in Al Hasakah Governorate. Elsewhere, in Daraa Governorate, rebel fighters captured the town of
Tafas from Ba'athist government forces after weeks of clashes which left scores dead. On 1 November, the Syrian Army retook control of the key city of
Al-Safira and the next day, the Syrian Army and its allies recaptured the village of Aziziyeh on the northern outskirts of Al-Safira. From early to mid-November, Syrian Army forces captured several towns south of Damascus, including Hejeira and Sbeineh. Ba'athist Government forces also recaptured the town of Tel Aran, southeast of Aleppo, and a military base near Aleppo's international airport. On 10 November, the Syrian Army had taken full control of "Base 80", near Aleppo's airport. According to the SOHR, 63 rebels, Army units were backed-up by Hezbollah fighters and pro-Ba'athist government militias during the assault. The following day, Ba'athist government forces secured most of the area around the airport. On 13 November, Ba'athist government forces captured most of Hejeira. Rebels retreated from Hejeira to
Al-Hajar al-Aswad. However, their defenses in besieged districts closer to the heart of Damascus were still reportedly solid. On 15 November, the Syrian Army retook control of the city of Tell Hassel near Aleppo. On 18 November, the Syrian troops stormed the town of Babbila. On 19 November, Ba'athist government forces took full control of Qara. The same day, the Syrian Army captured al-Duwayrinah. On 23 November, al-Nusra Front and other Islamist rebels captured the
al-Omar oil field, Syria's largest oil field, in Deir al-Zor Governorate causing the Ba'athist government to rely almost entirely on imported oil. On 24 November, rebels captured the towns of Bahariya, Qasimiya, Abbadah, and Deir Salman in Damascus's countryside. On 28 November, the Syrian Army recaptured Deir Attiyeh. On 2 December, rebels led by the Free Syrian Army recaptured the historic Christian town of
Ma'loula. After the fighting, reports emerged that 12 nuns had been abducted by the rebels. However, the FSA disputes this and said that the nuns had been evacuated to the nearby rebel held town of
Yabrud due to the Army shelling. In early December, the Islamic Front seized control of Bab al-Hawa border crossing with Turkey, which had been in hands of FSA. The groups also captured warehouses containing equipment delivered by the U.S. In response, the U.S. and Britain said they halted all non-lethal aid to the FSA, fearing that further supplies could fall in hands of
al-Qaeda militants. On 9 December, the Army took full control of Nabek, with fighting continuing in its outskirts. ==Rise of the Islamic State (January–September 2014)==
