LONDON (REUTERS) - British Foreign Secretary William Hague said on Monday it would be possible to respond to chemical weapons use in Syria without the unanimous backing of the United Nations Security Council.

"Is it possible to respond to chemical weapons without complete unity on the UN Security Council? I would argue yes it is otherwise it might be impossible to respond to such outrages, such crimes, and I don't think that's an acceptable situation," Mr Hague said on BBC radio.
