Sudan: Aid groups rush to help displaced from Abyei

International aid groups are rushing to provide assistance to tens of thousands of Sudanese civilians displaced by fighting in the disputed oil-rich Abyei area before seasonal rains hamper aid flows, aid groups said. Civilians fled the central town of Abyei during over a week of clashes between northern and southern troops earlier in May, prompting fears of further conflict just at the onset of the rainy season.
