Russian President Vladimir Putin has challenged the US to present to the UN evidence that Syria was responsible for chemical weapons attacks.
Mr Putin said it would be "utter rubbish" for Syria's government to provoke opponents with such attacks when it was in a position of strength.
US President Barack Obama has said he is considering military action against Syria based on intelligence reports.
