France's Fabius 'confirms sarin use' by Syria regime

There is no doubt Syria's government has used sarin during the country's crisis, says France's foreign minister.

Laurent Fabius said lab tests in Paris confirmed numerous uses of the nerve agent, adding that those who resort to chemical weapons must be punished.

But he did not specify where or when the agent had been deployed; the White House has said more proof was needed.

The UK also says it has tested samples which give evidence of the use of sarin in Syria.

According to a Foreign Office spokesman, Britain "has obtained physiological samples from inside Syria which have tested positive for the nerve agent sarin".

The UK statement added: "There is a growing body of limited but persuasive information showing that the regime used - and continues to use - chemical weapons" in Syria.
