Bombardment of rebel-held Aleppo areas kills 70 - Civil defence chief

BEIRUT (Reuters) - Heavy bombardment of rebel-held areas of eastern Aleppo has killed more than 70 people and has destroyed at least 40 buildings since Friday morning, Ammar al Selmo, the head of civil defence there, told Reuters. Warplanes targeted rebel-held districts of Aleppo in a second day of intense bombardment on Friday after the Syrian army declared an offensive to fully capture what was Syria's biggest city before the war.
