The US says it fears Syria's
President Bashar al-Assad may resort to using chemical weapons against his
people.
White House spokesman Jay Carney said the US was concerned that such an
action might be taken by "an increasingly beleaguered regime".
A Syrian official has insisted it would "never, under any circumstances" use
such weapons, "if such weapons exist".
