Combat operations in 2013 during the Battle of Aleppo
Battles in Aleppo and on its outskirts
Beginning in late 2012, fighting intensified around the area of the airport. The al-Nusra Front unilaterally declared a no-fly zone in December and threatened to shoot down commercial aircraft, alleging that the government was using them to transport loyalist troops and military supplies. After multiple attacks on Aleppo International Airport, all flights were suspended on 1 January 2013. Rebels attacked loyalist troops at the airport perimeter, including the nearby Brigade 80. By mid-February, at least 150 people had died in this fighting.Rebel troops attacked Menagh air base. On 30 December, government planes bombed rebel positions after the rebels entered the perimeter. On 14 January rebels had totally surrounded the base. Rebel troops stormed the base on 9 February, prompting retaliatory airstrikes. On 11 February, rebels stormed and took control of Jirah airbase, killing or capturing 40 soldiers. It was reported that rebels were in control of some operational Czech-built Aero L-39 Albatros jets.
In early 2013, the rebel offensive on the Old City persisted. By 12 January, army units had managed to gain control of the areas surrounding the historic Umayyad Mosque, the Citadel, and the Justice Palace near the Old City. However, by late February rebels had re-captured the mosque after days of heavy fighting, as government forces retreated to nearby buildings. Clashes continued afterward around the mosque.
On 15 January, twin blasts occurred at University of Aleppo during the first day of mid-terms, killing at least 87 and wounding more than 150, among them students and civilians. The university dormitories were used by refugees. Activists blamed government warplanes while the government blamed "terrorists". The Syrian government representative to the UN stated that 162 had been wounded. In the wake of the bombing, the Russian consulate in Aleppo temporary closed.
Belgian-born French journalist Yves Debay was killed during fighting on 18 January. Syrian State Media reported that rebels fired rockets at a building in the government-controlled Muhafaza Sakaniya neighbourhood, a claim that rebels denied.
On 29 January, the bodies of approximately 110 men and boys, most with bound hands and shot in the head were found on the banks of the Queiq River in the western district of Bustan al-Qasr, controlled by rebels. The victims were believed to have been detained, executed and dumped by government forces into the river over a period of several weeks. The bodies floated downstream from a government held portion of the river into a rebel area in Bustan al-Qasr. The bodies only became apparent when winter high water resided in late January. In February, a grate was placed over the river in rebel held territory to help catch other bodies floating down. Between February and mid-March, more than 80 additional bodies were dragged from the river. The continual appearance of these bodies the Queiq River to be referred to as "The River of Martyrs" by locals.
On 31 January, government warplanes bombed the Kurdish neighbourhood of Ashrafiyeh, controlled by the Popular Protection Units, killing at least twenty civilians and injuring 40. Sheikh Maqsoud was also reportedly shelled. Several days prior, on 28 January, a government tank reportedly fired a shell into the Kurdish sector of the city, killing one child and wounding two women.
In early January 2013, rebels laid siege to the strategic Police Academy in Khan al-Assal on the western outskirts, which was used by the government to shell nearby areas.
On 2 February, Sheikh Saeed district residents confirmed that rebels had taken control of the district after the Army withdrew, allowing the rebels to secure a key route to Aleppo International Airport. Sheikh Said was the last land route between Aleppo and Nayrab airport. Many of the neighbourhood's residents, who were largely loyal to the government, fled when the army retreated.
On 22 February, rebels alleged that three "Scud-type missiles" landed in the Hamra, Tariq al Bab and Hanano neighbourhoods with 29 confirmed dead and 150 wounded. SOHR later updated the toll, alleging that Scud missile strikes left 58 dead, including 35 children.
On 24 February, rebels used captured tanks to breach the walls and storm the Police Academy. Rebels took control of several buildings. Fierce clashes reportedly continued thereafter.
On 1 March, government forces retook Tel Shghaib village, located southeast of Aleppo. The following day, Army forces seized a road to the besieged airport, creating a new supply route for government forces advancing from Hama.
On 3 March, SOHR stated that 120 soldiers and 80 rebels were killed that week in the battle of the Khan al-Asal Police Academy.
On 4 March, rebels fully took over the police academy. They reported that about 45 government soldiers were killed, possibly executed, by rebels after they stormed the academy.
During March, an eight-day rebel offensive in an attempt to capture the village of Khan al-Assal on the western outskirts of the city was repelled. 200 fighters on both sides were killed in the offensive, including 120 government and 80 rebel fighters. Among government forces killed were 115 policemen, who the government alleged were executed by the opposition after capturing a police academy in Khan al-Assal.
On 15 March, rebels seized control of an ammunition factory complex and munitions depots in the town of Khan Tuman, southwest of Aleppo. The complex had been used to supply the Army with munitions to regularly shell rebel positions in the surrounding area.
On 19 March there was a chemical attack in Khan al-Assal, about 15 kilometers west of Aleppo, with about 26 fatalities. It was the first widely reported use of chemical weapons in the war. Both the government and rebels claim that a missile or rocket was used to deliver the agent. The Syrian Information Minister blamed the rebels for the attack, while the rebels blamed the government.
On the night of 29 March, the opposition Aleppo Media Center claimed that rebel forces had captured Sheikh Maqsoud, which was previously held by both government and Kurdish forces. However, SOHR stated that while rebel forces advanced into the district, they had captured only the eastern part. SOHR also reported that heavy fighting was still ongoing. It was also confirmed that during their advance, rebels had captured and killed the top pro-government Sunni cleric in the district, Hassan Seifeddine. Reports by pro-government Al-Ikhbariya TV and SANA stated he was beheaded and his head was placed on the minaret of the Al-Hassan Mosque. SOHR confirmed that his body had been dragged and paraded in the neighborhood.
On 31 March, government troops counterattacked. Fighting was concentrated by the Awarded bridge and in the area between eastern Sheikh Maqsoud and the Bustan al-Basha neighborhood. Since the rebel attack on the district started, 43 people had been killed, including 15 civilians, 19 government soldiers and militiamen and 9 rebels.
It was claimed by YPG fighters in Sheikh Maqsoud that following a long discussion within the group, the YPG decided to end their neutrality in Aleppo and switch to the rebel side, cooperating with the FSA in their advance through the district where several pro-government militias and intelligence officers were located. However, a day later, a YPG political representative denied the claim and stated that the Kurds had not aligned with the rebels, instead that Kurdish forces fought government troops after the Army attempted to reach Arab parts of the district that had been captured by opposition forces, via the Kurdish areas.
According to the YPG, as a result of these clashes, which also included artillery, 15 Syrian soldiers and one YPG fighter, YPG military council member Zekeriya Xelîl, were killed.
On 2 April, clashes erupted in the strategic village of Aziza, on the southern outskirts, from which rebels were launching attacks against Aleppo international airport and the adjacent military air base. By 6 April, the military had captured the village, pushing the rebels to the outskirts. Around 35 people were killed, including at least 18 civilians and 5 rebels. The capture of the village was seen as a strategic victory for the military because it would allow the Army to protect its supply convoys and have a strategic spot from which they could shell rebel positions.
On 13 April, nerve gas was reported in Sheikh Maqsood. An anonymous doctor reported three were dead and a dozen wounded. 1,500 doses of atropine were used with a further 2,000 sent by aid agencies. Atropine is a recognised antidote to nerve gases.
By 15 April, rebels had reportedly gained full control of the northern entrance to Aleppo, as well as a factory and a weapons storage facility.
On 16 April, the first Aleppo truce was declared. The temporary truce allowed Red Crescent workers to remove 31 decomposing bodies killed in the poor al-Sakhour district located in northern Aleppo. Three of the dead were found with tied hands and four were badly burnt.
On 22 April, two Syrian Christian Orthodox Bishops were kidnapped on their return to Aleppo after completing humanitarian work. State media blamed the rebels while the rebels stated, "all probabilities are open."
On 23 April rebels took control of a key position at the strategic Mennagh Military airbase, allowing them to enter the airbase after a months-long siege.
On 24 April, the 11th-century minaret of the rebel-held Great Mosque of Aleppo was destroyed in the fight. Rebels claimed that the Army destroyed the minaret with tank fire to prevent it becoming a sniper position, while the government claimed that it was destroyed by the Nusra Front.
On 4 May, the Siege of Menagh Air Base continued amid reports that rebels had made further advances. It was claimed that rebels had killed the base commander and also seized the second military detachment of the base. Rebels claimed that a group of pilots had defected and assassinated the base's commanding officer. The defectors told rebels that around 200 soldiers remained on base, garrisoned in the headquarters building and supported by a handful of tanks. Many soldiers resorted to sleeping under tanks, fearing a rebel assault.
On 9 May, it was reported that air strikes forced rebels to retreat from the air base.
On 15 May, rebel forces assaulted the main prison in central Aleppo where some 4,000 inmates were held. These include both common and political prisoners. The attack was initiated by twin car bombs at the prison entrance. Rebels secured one compound that housed government forces. The attack bogged down due to the intervention of Syrian tanks and planes. No prisoners were freed.
On 16 May, rebels were forced to retreat when soldiers began throwing inmate's bodies out of the windows. It was reported that rebel fighters took control of a building inside the prison after blowing up the main gate. Rebel fighters continued to hit the facility with rockets late into the night.
In early May, clashes started between rebel groups Ghuraba al-Sham and groups operating under Judicial Committee alliance. The latter accused Ghuraba al-Sham, which was in alliance with Jabhat al-Nusra, of going rogue and looting factories. According to various rebel reports Jabhat al-Nusra started weakening after Nusra leader al-Jolani pledged loyalty to Al-Queda leader Ayman al-Zawahiri. Before the announcements rebel fighters of various brigades were leaving for Jabhat al-Nusra, in one day about 120 left. Several rebel officials also commented on their disappearance from much of Aleppo.
A former government scientist claimed that the Syrian government was using chemical weapons in small quantities to slow rebel advances. Amongst these areas were the Sheikh Maksoud district. The scientist, who worked for Centre for Scientific Studies and Research, claimed that the alleged gas attack on Khan al-Asal, Aleppo, on 19 March 2013, was likely tear gas and not nerve gas. A UNHRC report dated 12 February 2014 concluded that the extremely deadly nerve agent sarin was used in the 3/19 Khan al-Asal attack and that the sarin used in that attack, bore the ‘same unique hallmarks’ as the sarin used in the 8/21 al-Ghouta chemical attack.
On 26 May, 15 inmates were killed, according to SOHR, at the central prison during fighting.
On 1 June, 50 prisoners were reported to have been executed by government soldiers, while a further 31 were killed by the rebel bombardment of the central prison. 40 government soldiers were killed by rebels.
On 2 June, a senior commander in the Lebanese movement Hezbollah, said that Assad's forces had called thousands of Hezbollah fighters deeper into Northern Syria, in and around Aleppo, to shore up Assad's overstretched forces and potentially break the stalemate there. It was estimated that around 4,000 Hezbollah fighters responded. Rebels said Hezbollah forces had entered the city on Sunday and were preparing an attack. An unnamed Hezbollah commander stated: “We are going to go after strongholds where they think they are safe. They are going to fall like dominos.”
The diversion of rebel forces to the Battle of al-Qusayr potentially weakened the rebel grip on Aleppo.
On 13 June, in a statement on recent clashes in the province of Afrin, in western Kurdistan, People's Defense Units Command said that Turkish soldiers attacked the village of Mele Xelîl in Afrin late Wednesday. YPG said, "The armed groups which first attacked our forces in the villages of Aqîn, Basil and Zarat increased in number as of June 10 when they attacked Meresk and Kefer Mezê villages. The armed groups were strongly responded and defeated by our forces". The Command remarked that YPG had strengthened its control as armed groups had to withdraw from the region after the clashes one day later. Referring to the Turkish attacks, YPG said "Troops of the Turkish military launched an attack against the village of Mele Xelîl in Afrin's Cindêris district late Wednesday in support of the armed groups targeting the region of Afrin." YPG said Turkish soldiers were repulsed from the region as a result of the response by YPG units.
