LONDON (Reuters) - British Foreign Secretary William Hague called on Wednesday for the United Nations Security Council to try to stop the bloodshed in Syria by agreeing a UK-backed resolution to take "necessary measures" there to protect civilians.

"We believe it's time the U.N. Security Council shouldered its responsibilities on Syria which for the last two and a half years it has failed to do," Hague told reporters, saying he feared Russia and China would block the resolution.
