International: 25 children among dozens killed in Syria gas attack

A suspected chemical attack killed dozens of people in a rebel-held area of Syria on Tuesday, activists said, describing an incident that would mark one of the worst of its kind in Syria's six-year civil war.

At least 83 people - including 25 children - died and at least 350 others were injured in the incident in northern Idlib province, southwest of Aleppo, the relief agency UOSSM told NBC News.

UOSSM, formally known as the Union of Medical Care and Relief Organizations, is a nonprofit coalition of groups treating to victims of the war in Syria.
