Syria: Rebel groups clash with each other in Aleppo
Syrian rebel factions fought each other in besieged eastern Aleppo on Thursday, officials from two of the groups and a war monitor said, potentially undermining their efforts to fend off a major Russian-backed offensive.
Rebel groups have been plagued by disunity and infighting throughout the 5 1/2-year-old conflict, for ideological reasons, over tactical differences or in disputes over territory.
Fighters of Jabhat Fateh al-Sham, Nour al-Din al-Zinki and Abu Amara attempted to seize positions and weapons from Fastaqim, one of its officials said. Fateh al-Sham is a jihadist group. Zinki and Fastaqim fight under the Free Syrian Army (FSA) banner.
