Hague confirms 'evidence' of Syria chemical arms plans
British Foreign Secretary William Hague says the UK and the US have seen evidence that Syria is preparing to use chemical weapons.
Mr Hague told the BBC there was "enough evidence to know that they need a warning".
Speaking to the BBC's Frank Gardner, the foreign secretary did not give details, as he said the evidence had come from "intelligence sources".
A Syrian official insisted last week that it would "never, under any circumstances" use such weapons.
