KALMA CAMP, Sudan (AP) -- The U.N. is warning that international aid can't go on forever for millions of displaced people in Darfur.
An official says the Sudanese government and rebels need to reach a solution that would let the refugees return home.
Humanitarian chief John Holmes made the comments as he visited Kalma camp, home to around 100,000 of the more than 2.5 million people displaced by fighting in the large region of western Sudan since 2003.
Earlier this month, Holmes appealed for $2.2 billion in donations to fund U.N. aid for Sudan, most of which would go to Darfur. The world body is providing food and other supplies for most of Darfur's 4.7 million people.
He says people are not dying of starvation, but "the problem is that people have been in camps for four or five years now." He says continued aid depends on the generosity of U.N. donors. Yet, as he puts it, "generosity has its limits."
Meanwhile, the president of Sudan is facing a possible arrest warrant from the International Criminal Court after prosecutors announced genocide charges against him.
