U.N. Secretary General Kofi Annan says Sudan's government made no progress last month in ending the crisis in the western Darfur region.
A new report by Mr. Annan says there was no positive action by Khartoum during the month of September in key areas essential for restoring security in Darfur, including disarming Arab militias and stopping attacks on civilians.
The U.N. Security Council will discuss the report Tuesday.
Darfur has been torn by violence since rebel groups began fighting government forces early last year. U.N. officials estimate the conflict has killed 50,000 people and left nearly 1.5 million others homeless.
U.S. official William Garvelink says the death toll from fighting and the humanitarian crisis could reach 300,000 this year.
