The UN-Arab League joint special envoy to Syria, Kofi Annan has announced he is leaving his post. In a news conference, he said the Syrian people "desperately need action" but criticised the UN Security Council for "finger pointing and name calling".

According to BBC, Mr Annan authored a six-point peace plan for Syria which was intended to bring an end to the fighting.

But the plan was never fully adhered to by either side and the violence has continued to escalate.

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.

Speaking to reporters in Geneva, Mr Annan said the increasing militarisation going on in Syria and the "clear lack of unity" in the Security Council had "fundamentally changed the circumstances for the effective exercise of my role".

He blamed both sides in the conflict, but said the problems were "compounded by the disunity of the international community".

"When the Syrian people desperately need action, there continues to be finger pointing and name calling in the Security Council," he said.

"It is impossible for me or anyone to compel the Syrian government, and also the opposition, to take the steps to bring about the political process.

"Syria can still be saved from the worst calamity - if the international community can show the courage and leadership necessary to compromise on their partial interests for the sake of the Syrian people - for the men, women and children who have already suffered far too much."

The veto-wielding members of the UN Security Council have failed to agree on what action to take on Syria.
