Kofi Annan resigned as the UN-Arab League special envoy to Syria on Thursday (August 2nd) and said the "disunity of the international community" hindered his attempts to implement his six-point peace plan.
"I did not receive all the support that the cause deserved," Annan told reporters at the United Nation headquarters in Geneva.
"The increasing militarisation on the ground and the lack of unanimity in the Security Council fundamentally changed my role," he said.
Annan said his eventual successor might have more success in persuading opposition and regime forces to lay down their arms, predicting that Syrian President Bashar Assad will leave office "sooner or later".
"I am still concerned for the Syrian people. They can still be saved. The men, women and children who have already suffered far too much," he said.
"We need a well-balanced political settlement to resolve this", Annan added.
Earlier, UN Secretary-General Ban Ki-moon had announced "with deep regret" that Annan had tendered his resignation from the mission.
"Kofi Annan deserves our profound admiration for the selfless way in which he has put his formidable skills and prestige to this most difficult and potentially thankless of assignments," Ban said, adding that he is in discussions with the Arab League on naming a successor.
