Obama has not decided on military action in Syria: US official

WASHINGTON (REUTERS) - US President Barack Obama has not made a decision to order military strikes against the Syrian government in response to last week's alleged chemical weapons attack near Damascus, a senior administration official said on Tuesday.

The assertion by the US official, which echoed the White House's comments on Monday, came amid mounting signs that Washington and its allies are edging towards a limited use of force against Syrian President Bashar al-Assad's loyalists.

Western powers have told the Syrian opposition to expect a strike against Mr Assad's forces within days, sources who attended a meeting between envoys and the Syrian National Coalition in Istanbul told Reuters earlier on Tuesday.

"The president has not made a decision to undertake military action," the US official in Washington told Reuters.
