BEIRUT - An explosion near a bus convoy waiting to enter the Syrian city of Aleppo killed or wounded several people on Saturday, pro-government media outlets, pro-opposition activists and a monitor reported.

The blast hit the Rashidin area on Aleppo's outskirts, where dozens of buses carrying mostly Shi'ite residents of two villages that are being evacuated in a deal between warring sides were waiting to enter the city.

Syrian state TV said an unknown number of people had been killed and wounded.

The British-based Syrian Observatory for Human Rights reported casualties, saying the explosion appeared to be caused by a bomb.
