REUTERS - Overnight bombardment of rebel-held eastern districts of Aleppo city killed 45 people, director of al-Quds hospital Dr. Hamza al-Khatib told Reuters on Thursday. 

Warplanes mounted the heaviest airstrikes in months against rebel-held districts of Aleppo overnight, rebel officials and the Syrian Observatory for Human Rights said earlier. 

There was no immediate comment from the Syrian military on the reports, or mention of airstrikes on Aleppo on state media.

U.S. Secretary of State John Kerry demanded on Wednesday that Russia and the Syrian government immediately halt flights over Syrian battle zones, in what he called a last chance to salvage a collapsing cease-fire and find a way "out of the carnage".
