Eight civilians including three children were killed on Thursday when unexploded munitions ignited at a house in northwestern Syria, a war monitor and the civil defence said.

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

"The final toll in an explosion of leftover war munitions in a house" in Idlib province is "eight dead including three children, one of them an infant, and two women", the Observatory said, adding another child was injured.

Syria's civil defence gave the same toll.
