Abyei is a territory of Sudan
On the border between South Sudan and Sudan, Abyei covers just over 10,000 square kilometres. Its special administrative status, mandated by a 2005 peace agreement, belies the simmering tensions that have fuelled violent inter-communal conflicts. [...] Abyei – a territory roughly the size of Jamaica – is being contested by two countries, Sudan and South Sudan. Abyei, which covers just over 10,000km², is under special administrative status following the terms of a 2005 peace agreement between the two countries. [...] In an effort to resolve the dispute over Abyei’s sovereignty, negotiations held between the Sudanese government and the Sudanese People’s Liberation Movement that began in 2002 proposed a referendum to decide if Abyei should become part of Sudan or South Sudan. Such a referendum would have been held in parallel with the South Sudanese independence referendum in 2011.
