WASHINGTON May 13 British Prime Minister David
Cameron said on Monday he wasn't ruling out taking tougher
action against Syria over growing evidence it was using chemical
weapons, saying he planned to raise the matter with U.S.
President Barack Obama.
"Certainly we haven't ruled out stepping up action in
response to what seems to be happening on the ground," Cameron
told NPR radio. "The evidence is growing; the lack of room for
doubt is shrinking, and I think this is extremely serious."
