(Adds OCHA confirms rape allegations paragraphs 7-8) KHARTOUM, Nov 21 (Reuters) - Sudanese officials ordered the Norwegian Refugee Council to leave South Darfur state, accusing the aid agency of espionage and publishing false information. "We have decided not to renew the technical agreement with Norwegian Refugee Council (NRC) in South Darfur state," Mohamed Salih, head of the international relations department of South Darfur, said on Tuesday. "They have made reports on military movements of armed forces ... which is in the domain of espionage," he told Reuters from Darfur. The NRC said last week it was pulling out of South Darfur because government obstruction and the suspension of its work meant it could no longer function in the region, where it helps some 300,000 people. Staff were still in Darfur on Tuesday. Salih accused the group of publishing a false report on 80 cases of rape around Kalma Camp, the state's largest and most volatile camp, which houses around 100,000 Darfuris. "The government of South Darfur with UNMIS (the U.N. Mission in Sudan) and OCHA (office for the coordination of humanitarian affairs) ... had a joint committee which came to the conclusion that this NRC report on 80 rapes was false," Salih said. U.N. spokeswoman Radhia Achouri denied that UNMIS was part of such a committee. The OCHA said it was part of the committee and supported NRC's rape report. "Actually many of the (rape) allegations were substantiated," an OCHA statement sent to Reuters said. The NRC was the camp coordinator for Kalma Camp. Kalma residents burned and looted the offices of government officials in the camp and authorities say rebels use it as a base for operations. Darfur is the world's largest humanitarian operation, with 14,000 aid workers trying to help some 2.5 million people who fled their homes to camps during fighting which experts estimate killed 200,000. U.N. humanitarian chief Jan Egeland's Darfur trip last week was cut short after government security forces said it was unsafe for him to visit areas outside the state capitals. He said government restrictions and military operations were endangering the entire Darfur aid operation.
