The immediate aftermath of the Aleppo bus convoy blast
The massive explosion hit buses carrying Shi'ite residents as they waited to cross from rebel into government territory as part of an evacuation deal between warring sides.
Those killed in the blast were mostly villagers fleeing al-Foua and Kefraya in Idlib province, but also included rebel fighters who were guarding the convoy.
There was no immediate claim of responsibility for the attack, which state media said was carried out by a suicide car bomber.
The convoy was carrying at least 5,000 people including civilians and several hundred pro-government fighters, who were granted safe passage out of the two Shi'ite villages which are besieged by rebels.
Under the evacuation deal, more than 2,000 people including rebel fighters were granted safe passage out of Madaya, a town near Damascus besieged by government forces and their allies.

That convoy was waiting at a bus garage in a government-held area on Aleppo's outskirts, a few miles from where the attack took place.
The evacuation deal is one of several over recent months that has seen President Bashar al-Assad's government take back control of areas long besieged by his forces and their allies.

SYRIA OPPOSES: President Bashar al-Assad's office denounced the U.S. strike as 'reckless, irresponsible behavior.'
The deals are unpopular with the Syrian opposition, who say they amount to forced displacement of Assad's opponents from Syria's main urban centres in the west of the country.
They are also causing demographic changes because those who are displaced are usually Sunni Muslims, like most of the opposition.
Assad is from the minority Alawite sect and is supported by Shi'ite regional allies.
