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.
