At least seven civilians, including a woman and a child, were killed on Thursday when unexploded munitions ignited at a house in northwestern 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, the Observatory said.
