Six killed in disputed region bordering Sudan, South Sudan

JUBA (Reuters) - Six people including a senior local administrator were killed in an ambush by armed men in the Abyei region claimed by both Sudan and South Sudan, local officials said.

The oil-rich region experiences frequent bouts of violence, where rival factions of the Dinka ethnic group - Twic Dinka from South Sudan's neighbouring Warrap State, and Ngok Dinka from Abyei - are locked in a dispute over the location of an administrative boundary.
