Kofi Annan to leave UN joint special envoy post
The UN-Arab League joint special envoy to Syria, Kofi Annan, has announced he is leaving his post.
He said it had become impossible for him to do his job, blaming the actions of the Syrian government as well as the opposition and what he called "disunity" among world leaders.
UN Secretary General Ban Ki-moon said it was "with deep regret" that he announced Mr Annan would not renew his mandate when it expires at the end of August.
