UN weapons inspectors have come under unidentified sniper fire as they investigated the site of an alleged chemical weapons strike on the outskirts of the Syrian capital Damascus.
The UN staff have been speaking to those injured in the attack.
Doctors on the ground are convinced that toxic agents were used in the assault:
Francoise Saulnier from Doctors Without Borders said: “Around 3,000 patients sought help in a few hours, so there was a massive contamination with patients showing symptoms of respiratory distress, convulsions, loss of consciousness and death. These are the clinical signs of poisoning by chemical agents.”
The US and its allies believe heavy government shelling in the area over the past five days will have destroyed any evidence of the toxic attack and permission to check out the site came too late.
