Cairo: In order to re-arrest a man who was previously convicted of killing a U.S. diplomat in Sudan 15 years ago, the United States asked the Sudanese government on Thursday. Abdel-Raouf A US Agency for International Development official named John Granville and his Sudanese driver, Abdel Rahman Abbas, were both murdered by Abu Zaid, a Sudanese man who was freed on January 30. State Department spokesman Ned Price said in a statement that Abu Zaid's release was based on untrue assertions. According to the Sudanese, the Granville family did not extend forgiveness, according to Price. "We demand that the Sudanese government use every legal tool at its disposal to overturn this judgement." Price emphasised that the imprisonment and sentence of Abu Zaid were not included in the 2020 agreement between the United States and Sudan.

The agreement was reached between the former transitional government of Sudan and the Trump administration in order to prevent any further compensation lawsuits against the African nation being brought in American courts. Granville, 33, was working to put into effect the 2005 peace accord that put an end to the more than 20-year civil war between the north and south of Sudan. Granville and Abbas were killed, along with him, when gunmen in another vehicle intercepted him as he was driving home from a New Year's Eve party.
