US officials say all U.S. government personnel were evacuated from Washington's embassy in Khartoum, as well as a small number of diplomatic personnel from other countries.
Under Secretary of State for Management John Bass said to reporters that they had evacuated all of the U.S. personnel and dependents assigned to Embassy Khartoum.
Bass said that a substantial number of local staff remain in Khartoum supporting the embassy, where Washington decided to suspend operations on Saturday due to the security risks.
Bass said some Americans and other nationals had successfully traveled by land from Khartoum to Port Sudan, which he said appeared to be a challenging journey given the lack of fuel, food and predictably available water.
Forces commanded by two previously allied leaders of Sudan's ruling council began a violent power struggle last weekend. Washington on Saturday repeatedly called on the parties to extend and expand a ceasefire for the Muslim Eid al-Fitr holiday to a sustainable cessation of hostilities.
Each side has accused the other of not respecting the truce.
