Saudi Arabia and the United States urged Sudan's warring parties on Sunday to agree to and “effectively implement” a new cease-fire as fighting showed no signs of abating in the northeastern African nation. Sudan descended into chaos after fighting broke out in mid-April between the military, led by Gen. Abdel-Fattah Burhan, and the paramilitary Rapid Support Forces, commanded by Gen. Mohammed Hamdan Dagalo. For weeks, Saudi Arabia and the United States have been mediating between the warring parties. On May 21, both countries successfully brokered a temporary cease-fire agreement to help with the delivery of much-needed humanitarian aid to the war-torn country.
