At least 43 people were killed today in a suicide car bomb attack on buses carrying Syrians evacuated from two besieged government-held towns. <br/><br/>The Syrian Observatory for Human Rights said the attack in Rashidin, west of Aleppo, targeted residents evacuated from the northern towns of Fuaa and Kafraya under a deal reached between the government and rebels. <br/><br/>More than 5,000 people who had lived under crippling siege for more than two years left the two towns. According to the Observatory, the bodies were still being recovered from the spot of the attack at a transit point in Rashidin.<br/><br/>Syria's war has left more than 320,000 people dead since the conflict started in 2011. More than half the population forced to leave their homes and hundreds of thousands endured siege-like conditions.
