DAMASCUS, May 15 (Xinhua) -- Over 40 civilians were killed by strikes of the U.S.-led anti-terror coalition on the city of Bukamal in the countryside of the eastern province of Deir al-Zour on Monday, pro-government Sham FM radio reported.

The report said the airstrikes targeted civilian areas in Bukamal city, which is controlled by the Islamic State (IS) group in Deir al-Zour.

The airstrike is the latest in a string of similar strikes that claimed the lives of civilians in the process of targeting IS positons.

Last Thursday, at least 11 people were killed and nine others wounded by a U.S.-led airstrike on the northern province of Raqqa.

The airstrike targeted one of the villages in the northern countryside of Raqqa, the de facto capital of the IS terror group, said the report.

The report said all those killed were civilians.

On Wednesday, at least 10 civilians were killed by U.S.-led airstrike against the town of Sour in the countryside of Deir al-Zour.

The U.S.-led anti-terror coalition has also been backing the Kurdish-led Syrian Democratic Forces (SDF) in their push against the IS positions in Deir al-Zour and Raqqa province.

The coalition previously acknowledged the falling of civilian victims by the airstrikes on IS-held areas in Syria.
