United Nations ? Sudan’s government is violating international humanitarian law by barring fuel, food and relief aid to civilians in Darfur, U.N. Secretary-General Kofi Annan said in a report released Monday.

The report to the U.N. Security Council described in frank terms how the people of Darfur have been exposed to more violence in recent months, even as aid groups are cutting the programs because of insufficient funding.

Government embargoes on goods entering areas of Darfur held by the rebel Sudanese Liberation Army “have prevented the access of civilians to vital goods and constitute a violation of international humanitarian law,” Annan wrote.

The report covered March and April but made clear that a May 5 peace deal signed between Sudan’s government and a main rebel faction has done little to bring solace to civilians in Darfur, where fighting has killed nearly 200,000 people and displaced 2.5 million since 2003.

Annan accused all parties in the conflict of also violating humanitarian law with “totally unacceptable levels of violence and despicable attacks against civilians,” even as final negotiations for the peace deal took place.
