(USA TODAY) -- Kofi Annan has resigned as special U.N. envoy to Syria, effective Aug. 31, after failing to get the two sides in the 17-month conflict to reign in the violence.
U.N. Secretary-General Ban Ki Moon says Annan had decided not to renew his mandate as U.N.-Arab League envoy to Syria when it expires at the end of August, the BBC reports.
Reuters reports that Annan blamed "fingerpointing and name calling" at the U.N. Security Council for his decision to resign.
Ban says Annan deserved "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."
The U.N. secretary general says he is in talks with the Arab League about a successor to Annan.
Neither side in the 17 months of fighting in Syria fully met the terms of Annan's six-point peace plan aimed at ending the violence that has killed thousands.
