North-South Clash in Sudan Kills 12 in Disputed Abyei Region VOA News May 03, 2011 At least 12 people were killed after a northern Sudanese army convoy entered the contested north-south border region of Abyei, sparking clashes with southern police. Abyei's top administrator, Deng Arop Kuol, says the fighting broke out Sunday when a Sudanese army convoy entered Abyei despite efforts by southern police to stop them. Kuol said a dozen people were killed including a policeman. In comments to Reuters news agency, a northern minister blamed the clashes on police, saying that troops were just joining an internationally recognized north-south force in the area. Each side regularly accuses the other of sending large numbers of soldiers into the disputed region. The oil-rich Abyei region was a battleground during Sudan's 21-year north-south civil war. South Sudan voted overwhelmingly to split from the north in a January referendum that northern leaders have said they will accept. However, the future of the Abyei region has yet to be resolved. Last week, Sudanese President Omar al-Bashir warned his government would not recognize south Sudan as an independent state it it did not give up claims on Abyei. A scheduled referendum on which part of Sudan Abyei would join failed to happen, because the north and south could not agree on who was eligible to vote. .
