Russia’s air force flew 141 sorties and hit 472 targets in Syria over the weekend, the RIA news agency quoted the country’s defence ministry as saying on Monday.

Russian jets hit targets in Aleppo, Damascus, Idlib, Latakia, Hama, Raqqa, Homs, and Deir Az Zor provinces, the ministry said.

On Sunday, Syrian government air strikes killed at least seven people, including three children, in Douma just outside of the capital Damascus, SOHR said.

It said at least seven civilians were killed on Saturday in government air strikes in Aleppo.

On Friday, Russia fired cruise missiles from the Caspian Sea for a fourth day against what it described as ISIL targets.

Russian and Syrian officials said their jets hit 50 ISIL targets in Deir Az Zor province, the most intense air raids since Russia began its air strikes.

Since last October, at least 42,234 air strikes that targeted farms, villages, towns and cities have been documented, according to SOHR.

It said over 22,370 so-called barrel bombs were dropped across the country in that period resulting in a total of 6,889 civilians deaths, including 1,436 children.

Another 35,000 civilians have been injured.

At least 100,000 people fled from Aleppo due to Russian air strikes, SNHR said, while another 1,000 fled a camp for the displaced in Atma, in Idlib city’s suburbs.

Russia says the goal of its military operation in Syria is in response to a request by Syrian President Bashar al-Assad and on the basis of a decision granted by its parliament.
