NNA - Seven civilians, including a woman and a child, were killed Thursday when leftover munitions exploded inside a house in northwest Syria, a war monitor said.

The Syrian Observatory for Human Rights reported the deadly blast a day after another organisation said two-thirds of Syrians risked being killed or wounded by unexploded ordnance.

"Seven civilians, including a woman and a child, were killed when leftover munitions stored inside a house" in Idlib province exploded, said the Observatory, adding the toll was provisional.

An AFP correspondent saw civil defence personnel working to remove rubble and pull victims from the destroyed house.

Mohammed Ibrahim, from the civil defence in Idlib, said they received a report "of an explosion of unknown provenance in Nayrab, and when teams headed to the site, they found unexploded ordnance".

Syria's conflict has killed more than half a million people and forced millions from their homes since erupting in 2011 with the brutal repression of anti-government protests.--AFP
