US-led air strikes in Syria kill 10 civilians, says Syrian Observatory for Human Rights

US-led forces which are bombing Islamic State militants in Syria killed ten civilians in two recent air strikes, a group monitoring the violence said on Saturday.

The Syrian Observatory for Human Rights said seven civilians were killed when an air strike hit a gas plant near the town of al-Khasham is the eastern Deir al-Zor province on Friday, and three civilians were killed in an air strike on Thursday night in the north east province of al-Hassakah.

Reuters cannot independently confirm the reports due to security restrictions.

The coalition has been bombing Islamic State targets in Iraq since August and extended the campaign to Syria in September. Close to 200,000 people have been killed in Syria's three-year civil war, according to the United Nations.
