Sudan's government is allowing Arab militias to maintain at least 16 camps in its Darfur region, despite promises to neutralize them, Human Rights Watch says.

In a report released Friday, the New York-based group says its investigators were able to gather information on the Janjaweed's extensive network of bases in Darfur.

The United Nations Security Council has given the government until Monday to act on its commitment to stop the Janjaweed from raping and killing black farmers in the region.

No sign of action

But Peter Takirambudde, executive director of the African division of Human Rights Watch, says there is no sign that Khartoum is taking any action.

"Throughout the time Khartoum was supposedly reining in the Janjaweed, these camps have been operating in plain sight," he said in the report. "These Janjaweed camps should be immediately investigated by the UN and the African Union ceasefire monitors, then disbanded."

Attacks by the Janjaweed have left tens of thousands of people dead and an estimated 1.4 million homeless.

Human Rights Watch says the Janjaweed and the Sudanese government army share five of the 16 camps they investigated.

The report adds that the government has incorporated members of the Janjaweed into the police and the army.

"If the United Nations is serious about seeing the Janjaweed disarmed, they've got to know where these militias are based," said Takirambudde. "Janjaweed and government forces take over villages they've driven people out of and from those bases continue their looting and killing."

The reports says that despite promises to disarm the militia, Khartoum has yet to produce a list of Janjaweed militia who have been disarmed or serial numbers of confiscated weapons.
