Fierce fighting in Yarmouk began on 5 December 2012 It was reported that at least 23 were killed, all civilians. About 1,000 Palestinians reached Lebanon less than 48 hours after the bombing. The new arrivals said they were now openly hostile towards the Syrian government that had long portrayed itself as the protector of Palestinians in Syria. Iran's
Fars News said that "terrorist" rebels had entered Yarmouk and shot dead "dozens of Palestinians and Syrian civilians". On 17 December, it was claimed that many PFLP-GC fighters defected to the rebels. One PFLP-GC commander said "I felt that we became soldiers for the Assad regime, not guards for the camps, so I decided to defect". He claimed that government forces stood by and watched as the PFLP-GC fought the rebels, without helping the Palestinians. Ahmed Jibril reportedly fled Damascus for the Mediterranean city of
Tartous. PFLP-GC political bureau member
Hussam Arafat, however, announced that Jibril was still in Damascus and that only a small number of fighters had defected. That day, rebel forces gained full control of Yarmouk as well as another Palestinian camp, with help from anti-Assad Palestinians, pushing out the pro-government PFLP-GC fighters. The pro-government PFLP-GC fighters were reportedly overwhelmed and suffered great losses as they were unable to evacuate their wounded due to rebel snipers on the roofs. PFLP-GC member Anwar Raja reportedly played a major role in working out a strategy to besiege the largely-rebel held camp from this point onward. Shortly after, government and rebel representatives agreed that all armed groups should withdraw from Yarmouk and leave it as a neutral zone. The agreement also said that the PFLP-GC should be dismantled and its weapons surrendered. However, a spokesman for the pro-rebel Palestine Refugee Camp Network said, "the implementation of the truce has been problematic" because of "intermittent" government shelling of Yarmouk and clashes on its outskirts. An AFP reporter at Batikha, the main entrance to the camp, reported sporadic shooting on 21 December but no gunmen were seen on the streets of Yarmouk. ==Aftermath==
