Watch: Recent strike in Syria suspected to be a chemical attack

A suspected chemical attack in rebel-held northwestern Syria on 4 April, killed dozens of civilians including children and left many more sick and gasping for air. The United States, Britain and France blame the Bashar al-Assad’s government, even as the Syrian Army denies any role in it. The attack left hundreds suffering from respiratory problems and symptoms including vomiting, fainting and foaming at the mouth, Britain-based Syrian Observatory for Human Rights said.
