Tens of thousands of residents in the remote and disputed Abyei border region voted on Monday in a non-binding referendum on whether to join Sudan or South Sudan despite fears it could trigger violence. The ownership of Abyei was left undecided when South Sudan declared independence from Sudan in 2011 and a long-promised official plebiscite on its status has been stalled by arguments over can vote, prompting the local referendum initiative.
