At least 106 civilians, including 42 children, have been killed in a series of air strikes by the US-led coalition on an ISIL-held town in eastern Syria, according to a monitoring group.

The British-based Syrian Observatory for Human Rights says the deaths resulted from air strikes targeting Al Mayadeen in the province of Deir Az Zor.

Between April 23 and May 23 this year, US coalition strikes have already killed a total of 225 civilians in Syria, including dozens of children.
