U.S. military option on Syria not off the table - senior administration official

WASHINGTON (Reuters) - The United States has not excluded a military response to a poison gas attack that killed scores of civilians which Washington blamed on the Syrian government, a senior administration official said on Thursday.

Asked whether the military option had been taken off the table, the official said: "No."

    It is unclear how much U.S. military planning exists on striking targets associated with Syrian President Bashar al-Assad's government.
