Syrian government forces and allied fighters advanced further into rebel-held Aleppo on Monday, pressing an offensive in defiance of international concern for the fate of the city and its beleaguered civilians.
"At least 36 people were killed in Monday's bombing," rescue worker Ibrahim Abu Leith told Al Jazeera. "These are the most violent attacks we've seen in five years."
The recapture of the rebel-held east, which fell from government control in 2012, would be the government's most significant victory since the conflict began more than five years ago.
Rebel forces have steadily lost ground since Moscow, a key backer of President Bashar al-Assad, intervened to bolster his government last year.
