Syrian aircraft drop barrel bombs on rebel-held Aleppo, killing at least 15

Syrian activists say government military aircraft dropped barrels bombs on a rebel-held area in the northern city of Aleppo, killing at least 15.

The activist collectives, the Local Coordination Committees and the Aleppo Media Center, reported the Saturday bombings in Masaken Hanano. The Local Coordination Committee reported 20 people killed, while the Aleppo Media Center reported 15 killed. It is normal for activists to give different death tolls following bombings.

The crude bombs — cylinders packed with explosives and shrapnel that are hurled from helicopters — blew apart a building, according to footage uploaded by activists to social networks. The footage corresponded to The Associated Press reporting of the event.

Syrian forces have been relentlessly bombing rebel-held areas of Aleppo, trying to wrest full control over the city.
