Syrian offensive kills scores in Aleppo before Swiss talks

Syria's military backed by Russian warplanes have killed more than 150 people in eastern Aleppo this week, rescue workers said, part of a renewed bombardment supporting an offensive to seize the city's shattered rebel-held sector.
As air strikes and shelling of the city's east intensified since Tuesday after a brief period of relative calm, Syria's government approved a UN plan to allow aid convoys into most besieged areas of Syria, with the exception of Aleppo.
Rising casualties in Aleppo, where buildings have been reduced to rubble or are lacking roofs or walls, have prompted an international outcry and a renewed diplomatic push, with talks between the United States and Russia planned for Saturday.
