The U.N. mission in Libya said Wednesday that warring parties in the eastern city of Benghazi have agreed to a 12-hour humanitarian truce. U.N. special representative Bernardino Leon said the cease-fire began Wednesday morning and could be extended by the parties. The cease-fire is a "much-needed reprieve from the violence," Leon said in a statement, adding that the Red Crescent will evacuate civilians from affected areas and retrieve bodies of those killed in recent fighting. It was not immediately clear if violence in Benghazi calmed after the U.N. announcement.
