Beirut – The death toll from a bomb blast on a crowded Syrian bus convoy outside Aleppo on Saturday reached at least 112 people, the Syrian Observatory for Human Rights monitoring group said.

Syrian rescue workers the Civil Defence said that they had carted away at least 100 bodies from the site of the blast, which hit buses carrying Shi'a residents as they waited to cross from rebel into government territory in an evacuation deal between warring sides.

The British-based Observatory reported its new toll early on Sunday and said the number was expected to rise.
