The US-led coalition against the "Islamic State" (ISIS) terrorist group hit a weapons depot belonging to a rebel group allied with Al-Qaeda's Syrian affiliate overnight in northwestern Syria, a monitor said Wednesday, according to AFP.

The strikes killed 10 members of the Jaish al-Sunna group, as well as a child, the Syrian Observatory for Human Rights said.

The raid hit the Atmeh region of Idlib province, home to a large camp for displaced Syrians, but did not strike the camp itself, Observatory director Rami Abdel Rahman said.
