A six car convoy of cars have left the Four Seasons hotel in Damascus and are headed to the scene of an alleged poison gas attack outside the Syrian capital last week. A Reuters witness said.
The team of chemical weapons experts, dressed in blue UN body armour, were accompanied by security forces and an ambulance.
They said they were headed to an area called Eastern Ghouta, a rebel-held area on the outskirts of Damascus, where activists said rockets loaded with poison gas killed hundreds of people.
