NEW YORK, Aug 27 (Reuters) - U.S. stocks fell on Tuesday as geopolitical tensions flared on the possibility of an impending military strike against Syrian President Bashar al-Assad's forces in response to a chemical weapons attack against civilians last week.
Western sources who attended a meeting in Istanbul between envoys of an alliance opposed to Assad and the Syrian National Coalition said "action to deter further use of chemical weapons by the Assad regime could come as early as in the next few days."
Adding to the rising tension, Defense Secretary Chuck Hagel said in a television interview with the BBC the U.S. military forces in the region are "ready to go" should President Barack Obama order action against Syria.
