A series of barrel bombs dropped by Syria's regime killed at least 45 civilians and wounded dozens in Aleppo province on Saturday, said the Syrian Observatory for Human Rights.
"At least 45 civilians were killed, and dozens were wounded, when regime helicopters dropped barrel bombs on the city of Al-Bab and in eastern neighbourhoods of Aleppo," the Britain-based Observatory reported.
Al-Bab, about 40 kilometres (25 miles) northeast of Aleppo city, is controlled by the extremist Islamic State group, while the east of the provincial capital is in rebel hands.
