United Nations Secretary-General Kofi Annan says a peace agreement that ended the civil war in southern Sudan appears to be floundering.
In a report released late Tuesday, Mr. Annan said many important pledges have not been fulfilled.
The Khartoum-based government and the southern Sudan People's Liberation Army signed the peace agreement in January 2005, ending 21 years of civil war.
Mr. Annan says both sides have been observing security commitments "reasonably well," but they have not embraced all the provisions of the pact.
He says plans for elections, as well as power and wealth sharing, have not been met.
The U.N. secretary-general also notes that international donors have only provided a fraction of the money needed to rebuild southern Sudan.
