The ICRC, an independent humanitarian agency, said it was appalled by reports of a poison gas attack on Aug. 21 that left hundreds dead -- which the U.S. said was carried out by President Bashar al-Assad's regime. A U.N. investigation at the site of the alleged attack is ongoing. The ICRC urged warring parties in Syria's two-year civil war to respect the absolute ban on chemical weapons use under international law.
Magne Barth, head of the ICRC's delegation in Syria, said proposed Western military action would "likely trigger more displacement and add to humanitarian needs, which are already immense." Some 2 million people have already fled Syria, including 1 million children. Human rights groups estimate that 100,000 people have been killed since the war began.
Areas plagued by heavy fighting -- including the countryside around Damascus, eastern Aleppo and Deir Ezzor province -- are also reeling from breakdowns of basic services such as water, electricity and garbage collection, the ICRC said in a statement.
"In large parts of rural Damascus for example, people are dying because they lack medical supplies and because there are not enough medical personnel to attend to them," said Magne Barth, head of the ICRC's delegation in the country. "They also go hungry because aid can't get through to them on a regular basis."
