A Sudanese rebel group Thursday declared a three-month cease-fire in southwest Sudan to allow deliveries of relief food to hundreds of thousands of people.

Several hours later, the Sudanese government said it, too, had agreed to a truce - but only for a month. The Sudanese news agency said President Omar el-Bashir of Sudan approved the cease-fire at the request of Kenya's president."This is a humanitarian truce limited to areas afflicted by famine and has nothing to do with issues of war and peace in southern Sudan," said Pa'gan Amum, an official of the Sudanese People's Liberation Army. The cease-fire applies to Bahr el-Ghazal province.

The U.N. World Food Program said fighting between rebels and government troops in Sudan has driven thousands of people from their villages. Millions are threatened by civil war and famine.
