Heglig is a territory of Sudan
Heglig, or Panthou (also spelled Heglieg or Pandthow), is a small town at the border between the South Kordofan state of Sudan and the Unity State in South Sudan. The entirety of Heglig is claimed by both Sudan and South Sudan, but administered by Sudan. The area was contested during the Sudanese Civil War. In mid-April 2012, South Sudan's Sudan People's Liberation Army (SPLA) captured the Heglig oil field from Sudan.[1] Sudan took it back at the Second Battle of Heglig ten days later.[2] [...] In July 2009, the international organization, Permanent Court of Arbitration (PCA) redefined the boundaries of Abyei, a county that lies between South Sudan and Sudan. The decision placed the Heglig and Bamboo oilfields out of Abyei boundary but did not specify to be belong to the Sudan province of South Kordofan, nor to Upper Nile region, South Sudan and also the decision did not specify oil sharing. The government of Sudan claimed that area is belong to its country since it was ruled to be out of Abyei boundary by PCA and announced they would not share any oil revenue with the Government of South Sudan, emphasizing that the PCA established that Heglig was part of the north. The document of the PCA only indicated that the Heglig or Panthou area is not part of Abyei.
