Sudan's foreign minister said on Wednesday he saw no reason why two international aid workers had been arrested for crimes against the state and pledged to solve the problem in talks with the United Nations. Sudan this week arrested then released on bail two workers from the Dutch branch of Medecins Sans Frontieres (MSF) on charges of spying, publishing false information and destabilising Sudanese society, according to Reuters. "I agreed with (U.N. envoy) Jan Pronk yesterday that there was no reason for the arrest of the two employees of the organisation and they will likely be released," Foreign Minister Mustafa Osman Ismail told reporters in Khartoum. The two men are free but cannot leave Khartoum. "When we come back from Rwanda I will meet Pronk and I will talk to him about how to find a solution to this problem," he said. He is due to return next week from the capital Kigali.
