ATTENTION EDITORS - VISUALS COVERAGE OF SCENES OF DEATH AND INJURY
Relatives and activists inspect the bodies of people they say were killed by nerve gas in the Ghouta region, in the Duma neighbourhood of Damascus August 21, 2013 in this handout provided by Shaam News Network. Syrian activists accused President Bashar al-Assad's forces of launching a nerve gas attack that killed at least 213 people on Wednesday, in what would, if confirmed, be by far the worst reported use of poison gas in the two-year-old civil war. Reuters was not able to verify the accounts independently and they were denied by Syrian state television, which said they were disseminated deliberately to distract a team of United Nations chemical weapons experts which arrived three days ago.
