Between 27 and 29 October 2013 an informal, non-binding vote was held, although unrecognised by either Sudan or South Sudan. Only the Ngok Dinka tribe participated, with the Arab Misseriya tribe boycotting, claiming it would not recognise the result. The vote followed UN and AU warnings that such a move could inflame tensions.[8] As counting took place, the Misseriya vowed to carry out its own such referendum.[9] The spokesman for the Abyei Referendum High Committee, Luka Biong, announced that of those who voted, 99.9% supported joining South Sudan; this was then followed by celebrations.
