The United Nations Security Council must find a way to “unlock” the situation in Sudan’s South Kordofan and Blue Nile States so that humanitarian agencies can gain unfettered access to administer polio vaccinations to as many as 165,000 children in the two states, John Ging, Director of Operations from the UN Office for the Coordination of Humanitarian Affairs, said at a press conference at UN headquarters in New York yesterday. Despite the outbreak of polio in the region, Sudanese government and rebel forces there have not responded positively to the urgency of the situation, he said.
