Doctors who treated children affected by a chemical weapons attack in northern Syria on Tuesday have spoken out about the devastating scenes they witnessed.
At least 72 civilians, including 20 children, were killed in what is feared to be the worst chemical weapons attack in Syria in almost four years, according to the Syrian Observatory for Human Rights.
Hospitals treating victims of a suspected toxic gas were themselves targeted in a series of air strikes following the atrocity in a rebel-held town in Idlib province, where activists claimed up to 100 people died.
At a hospital in Idlib, about 30 miles away from Khan Sheikhoun, the town that was hit, Doctor Mizar Hassani said he treated around 30 patients, among them four children.
Dr Tennari said many of the injured died immediately, most of them choking on gas, while others died on their way to the hospital where some survived and were treated.
