Syrian rebels 'sceptical' of US strike

Any US military action against Syria would amount to "support for al-Qaeda and its affiliates," Damascus has said.

Syrian Deputy Foreign Minister Faisal Mekdad also told the BBC that armed groups backed by America - not Syrian troops - had used chemical weapons.

The US says it has evidence that Damascus used the nerve agent sarin in a deadly attack in August - but Barack Obama has said he wants Congress to vote on any possible military intervention.

Syrian opposition forces say they are sceptical that any attack will take place, as Emily Buchanan reports.
