Earlier in the day, a blast occurred near a bus convoy evacuating residents of the besieged Shiite towns of Fua and Kefraya to Aleppo. The previous death toll was 20 with 50 others injured.
“The number of victims is at least 70; over 130 are injured. It is difficult to say as there are many burnt bodies and body parts around the damaged buses,” according to the source on site.
According to the souce, there are many children and women among those killed.
The explosion hit the Rashidin area on Aleppo’s outskirts. The bus was waiting for entering the city of Aleppo.
The blast supposedly was caused by a suicide attacker who detonated an explosive device. The car with the attacker approached the buses disguised as a vehicle transporting food.
The evacuation of Fua and Kefraya residents is a part of a deal between the Syrian government and militants.
On Friday, a convoy of 75 buses arrived in Aleppo, evacuating some 5 thousand people from the besieged cities.
