BEIRUT: Syrian activists say 51 people, including 13 rebels, have been killed in a single day of government airstrikes and shelling of opposition-controlled districts of Aleppo.
The Britain-based Observatory for Human Rights says most of the victims died from airstrikes and barrel bomb dumped on eight rebel-held districts of the northern city on Wednesday. The rest died from artillery shelling and sniper fire.
The Observatory has been documenting Syria's conflict since its start in March 2011 through a network of activists on the ground.
It released its report on the latest Aleppo casualties on Thursday, ahead of a trilateral meeting between U.S., Russian and U.N. official with Syrian government and opposition representatives in Geneva.
The international mediators are trying to salvage the faltering peace negotiations.
