JUBA - The United Nations said on Tuesday it had started airdrops to deliver emergency food to a camp in South Sudan packed with people fleeing fighting on the Sudan side of the joint border.
Fighting broke out between the Sudanese army and rebels of the SPLM-North in South Kordofan state around the time of South Sudan's independence in July 2011. It then spread to nearby Blue Nile state in September.Sudan accuses South Sudan of supporting the SPLM-North, which says it is marginalized in the Arab country. The South denies any links to the rebels, but some Western diplomats say they find Khartoum's claims credible.
The United States and aid groups have warned there is a risk of famine in both states, especially in areas held by rebels.
More than 170,000 people have fled to South Sudan, where they stay in crowded makeshift camps near the border, the UN World Food Program said.
