South Kordofan State is now the epicenter of the war in Sudan, which has caused the world’s largest humanitarian crisis, warned the international humanitarian organization Norwegian Refugee Council (NRC) on Monday. Civilians in this part of southern Sudan face intensified hostilities and a nearly total blockade of humanitarian supplies after a year of starvation and bombardment, said NRC Secretary General Jan Egeland at the end of his visit to South Kordofan.
