Air strikes and barrel bomb attacks killed 16 civilians in rebel-held parts of Aleppo province on Monday, with rebel rocket fire onto government areas killing three more, a monitor said.
The Britain-based Syrian Observatory for Human Rights said 10 civilians had been killed in multiple air strikes on the town of rebel-held Atareb in Aleppo province.
The group said the strikes in the early hours of Monday morning were believed to have been carried out by Russian warplanes, and hit several locations including a market area.
