Air raids in the northern part of Syria on Tuesday killed at least 39 people, mostly civilians, the Syrian Observatory for Human Rights said. Russia was suspected to have carried out the strikes, it added. Russia began bombing the country late in September in its war against the Islamic State.

AFP reported that the raids targeted a market in a village in the province of Idlib, and another in a northern Aleppo province village held by IS. The toll is likely to rise.

Airstrikes also killed 45 people, including several children on Sunday, after explosions hit an area near a school in Douma (pictured above). Over 10 million people have fled Syria since the civil war began, and more than 2,50,000 people have been killed.
