The UN mission in Sudan called on Khartoum on Wednesday to withdraw its decision to prevent 50 German military observers from entering the country to take part in the international peace mission, said Sudanese Foreign Minister Mustafa Othman Esmaeil on Wednesday. Esmaeil told reporters that he discussed the issue with UN Secretary General's Special envoy for Sudan, Jan Pronk, indicating that both sides agreed to deal with the issue within the framework of rescuing the peace process and aiding the UN's role in this regard. He said the decision to prevent German observers from entering Sudan was due to the entry of the German state minister to the country without a visa, considering such a step as a violation of the Sudanese sovereignty. Unless Berlin comes up with an explanation for this irregular act, Khartoum will not allow any German official, military or civil, to enter the country, he added.Since last May, the UN has deployed 10,000 peace keeping soldiers in Sudan, in addition to 715 civil policemen, based on the UN Security Council's resolution 1590 of last March which delegated the UN mission in the country to observe the implementation of a peace agreement, reached between Khartoum and rebels last January.
