The blast was reportedly caused by a suicide attacker detonating a car bomb. While Syrian state media said at least 39 were killed, sources on the ground told Xinhua that at least 70 people died and 128 others injured in the bomb attack. That number was confirmed by another source to RIA.
Pictures have emerged on social media purporting to show the aftermath of the blast.
Humanitarian workers were among the victims of the attack, according to Arabic Asharq Al-Awsat.
Very graphic footage from the scene posted online shows burned out vehicles with the dead lying on the ground and inside buses, some covered with blankets.
“A very powerful blast” killed “many women and children” inside the buses, an eyewitness said while filming the video. There were also fighters from the Free Syrian Army and other groups who were securing the area among the victims, he added.
