Sudan appears to be in a civil war “of the most brutal kind” and the world needs a new forum for talks in pursuit of a cease-fire, the United Nations humanitarian chief told The Associated Press on Monday. Martin Griffiths spoke as regional leaders met in neighboring Ethiopia following the breakdown of peace talks in Saudi Arabia in June. Egypt says it will host leaders from Sudan's neighbors on Thursday in search of peace, with few details. “We don't have a place, a forum, where the two parties are present ... where we can broker the kind of basic agreements that we need to move supplies and people,” Griffiths said. He called Sudan the toughest place in the world for humanitarian workers in terms of access and warned that the crisis will only worsen as the fighting spreads to new areas.
