In 2009, General Martin Luther Agwai, head of the UNAMID, said the war was over in the region, although low-level disputes remained. "Banditry, localised issues, people trying to resolve issues over water and land at a local level. But real war as such, I think we are over that," he said. This perspective is contradicted by reports which indicate that violence continues in Darfur while peace efforts have been stalled repeatedly. Violence between Sudan's military and rebel fighters has beset Southern Kordofan and Blue Nile states since disputed state elections in May 2011, an ongoing humanitarian crisis that has prompted international condemnation and U.S. congressional hearings. In 2012, tensions between Sudan and South Sudan reached a boiling point when the Sudanese military bombed territory in South Sudan, leading to hostilities over the disputed Heglig (or Panthou) oil fields located along the Sudan-South Sudan border.
