US Secretary of State Colin Powell has warned senior Sudanese officials that President Bush and other foreign leaders "remain completely dissatisfied" with Khartoum's efforts to end the violent campaign by Arab militias in Darfur, Sudan.
Mr Powell said he told first vice president Ali Uthman Muhammad Taha and Foreign Minister Mr Mustafa Osman Ismail that the government has not done enough to control the Arab militias, known as the Janjaweed, believed responsible for killing tens of thousands of black Africans in Darfur and driving more than one million from their homes.
The Sudanese government has responded to some extent to pressure in recent weeks from the United States, other countries and the United Nations, which are demanding a halt to the violence and better access for relief workers trying to feed and care for homeless civilians. But Mr Powell and UN relief agencies say violence against civilians continues.
"While I took note of some marginal improvement in the humanitarian side," Mr Powell said, "I also pointed out to them as clearly as I could that I, the president and the international community remain completely dissatisfied with the security situation. Not enough is being done to break the hold of the Janjaweed.
"Rapes are still occurring," Mr Powell added. "People do not feel safe leaving the camps to go out and forage for food. The situation remains very, very serious, and first and foremost the security has to be dealt with."
The crisis in Sudan began in February, when two rebel groups in Darfur took up arms against the Khartoum government, citing mistreatment of the region's main black African tribes. Human rights groups charge that Sudanese officials have organized the region's Arab tribes into an armed militia, and provided them with military and political support as they carried out an ethnic cleansing campaign against the rebels' followers.
US Ambassador to the United Nations Mr John Danforth met with senior UN officials in New York, including UN Secretary General Kofi Annan's personal envoy, Mr Jan Pronk, to keep the pressure on Sudan.
Mr Pronk, who returned this week from a visit to Khartoum, is to brief the 15-nation Security Council today.
