A suicide car bomb attack on buses carrying Syrians evacuated from two besieged government-held towns killed 43 people on Saturday, as US-backed fighters advanced in their push towards the Daish’s Raqa stronghold.
The Syrian Observatory for Human Rights said the blast targeted buses carrying residents evacuated from the northern towns of Fuaa and Kafraya under a deal reached between the regime and rebels.
Bodies were still being recovered from the attack at a transit point in Rashidin, west of Aleppo, according to the Observatory.
“The suicide bomber was driving a van supposedly carrying aid supplies and detonated near the buses,” the monitoring group said.
It said that most of the dead were evacuees, but also included several rebels who had been guarding the buses.
Thousands of evacuees had been stuck on the road because of a disagreement over the number of rebels allowed to leave two other towns included in the deal, but the process restarted following the blast, the Observatory said.
A reporter in rebel-held Rashidin saw several bodies, body parts and blood scattered on the ground.
The bombing took place as thousands of evacuees from Fuaa and Kafraya waited to continue their journey to regime-controlled Aleppo, the coastal province of Latakia, or Damascus.
More than 5,000 people who had lived under crippling siege for more than two years left the two towns, along with 2,200 evacuated from rebel-held Madaya and Zabadani, on Friday.
US-backed fighters reached the outskirts of a key radicals-held town in northern Syria on Saturday as part of an offensive aimed at the Daish bastion of Raqa.
The Syrian Democratic Forces (SDF), an Arab-Kurdish alliance supported by US-led coalition air strikes and special forces advisers, surrounded Tabqa in early April and have cut its main supply routes.
The town and a vast nearby dam are considered key prizes in the broader offensive for Raqa, the de facto Syrian capital of Daish’s self-proclaimed “caliphate”, about 55 kilometres to the east.
An SDF military source said Saturday that clashes were fierce and that the alliance’s forces were “trying to penetrate the town from the east and west”.
The alliance was reported to have advanced overnight after driving the radicals from two areas just southeast and southwest of the town.
SDF fighters are within a few hundred metres of Tabqa, said Observatory head Rami Abdel Rahman.
He said heavy clashes were under way around the two suburbs as IS attempted to counter-attack.
The SDF launched its campaign for Raqa in November and has since captured most of the surrounding province.
