The US has proposed a UN Security Council resolution that would impose an arms and travel embargo on the Janjawid militia which is blamed for the bloodshed in Sudan's troubled Darfur region.
The draft does not spell out sanctions against the Sudanese government, which is said to have supported the militia in creating what UN officials call the worst humanitarian catastrophe in the world today.
US Secretary of State Colin Powell yesterday called on Sudan's leadership to address the situation in the western region of Darfur.
Arab militias have been driving hundreds of thousands of people from their homes in the region.
More than 10,000 people have died in Darfur since a revolt against the Arab-dominated government in Khartoum by African indigenous minorities in February of last year.
On a visit to the country, Mr Powell said the Sudanese government must crack down on the militias or face unspecified UN Security Council action.
