TOPSHOT - A Syrian child receives treatment at a small hospital in the town of Maaret al-Noman following a suspected toxic gas attack in Khan Sheikhun, a nearby rebel-held town in Syria's northwestern Idlib province, on April 4, 2017. Warplanes carried out a suspected toxic gas attack that killed at least 35 people including several children, a monitoring group said. The Syrian Observatory for Human Rights said those killed in the town of Khan Sheikhun, in Idlib province, had died from the effects of the gas, adding that dozens more suffered respiratory problems and other symptoms.
