Barrel bombs kill at least 15 funeral mourners in Syria's Aleppo

At least 15 funeral mourners were killed in a barrel bomb attack on a rebel-held district of Syria's Aleppo on Saturday, as the UN envoy for Syria called for all warring sides to agree by Sunday to allow the first safe delivery of relief supplies to the divided city.

The Britain-based group Syrian Observatory for Human Rights monitor said government aircraft dropped two explosive-packed barrel bombs several minutes apart on the Maadi district of eastern Aleppo.

Syrian civil defence, a volunteer rescue group, told Al Jazeera that Syrian government aircraft hit a group of people gathered in the al-Maadi neighbourhood to mourn the deaths of 15 women and children killed in a raid earlier this week. 

The strikes hit "near a tent where people were receiving condolences for those killed this week in the neighbouring district of Bab al-Nayrab," Observatory director Rami Abdel Rahman said.

"There was a first barrel bomb, and when people gathered and the ambulances arrived, a second barrel struck and there were more deaths," an AFP reporter in the rebel-held part of the city said.
