Syria's army retook control of a historic mosque in the northern city of Aleppo on Sunday after fierce clashes with rebels, a military official and an observer group said. 

As casualties mount, Aleppo's few operating hospitals are struggling to cope with the number of victims, mostly civilians, caused by several months of fighting between government forces and Syrian rebels.
