Air strikes carried out by unidentified aircraft killed at least 22 civilians, including 10 children, in a village held by the Islamic State group in eastern Syria, a monitor said on Wednesday. The Syrian Observatory for Human Rights said the civilians were from two families at Hojna in Deir Ezzor, which borders Iraq and is the country’s second biggest province after Homs. The oil-rich province of Deir Ezzor is under IS control and has been regularly targeted by a US-led military coalition.
