As foreign countries continue to evacuate their citizens from Sudan by land, sea and air, Sudanese citizens report gunfire and heavy artillery fire in parts of Khartoum on Saturday.  

The military activity continues amid the extension of a ceasefire between the country's two top generals, warring with each other for power. Hundreds of Sudanese civilians thronged the borders as renewed warnings grow louder of the wider instability to come if the fighting does not stop. At least 528 people have been killed and 4,599 wounded, with the United Nations saying it believes the real toll is much higher.

At least 75,000 people have been internally displaced by the fighting, the UN said. Satellite views shows buses gathered at the Arqeen border crossing into Egypt.

The UK said Saturday 1,888 people were airlifted to safety in its evacuation effort, while the U.S. State Department reported hundreds of Americans reached Port Sudan safely in its first evacuation on Saturday.  

The U.S. earlier received criticism from families of Americans in Sudan for initially ruling out any U.S.-run evacuation.

The first charter flight carrying more than 340 Chinese nationals evacuated from Sudan arrived in Beijing on Saturday morning.
