The United Nations is warning that more than 800,000 people could flee Sudan, due to the ongoing clashes between rival military factions.
Fighting is continuing in the capital of Khartoum, despite promises of a ceasefire between the two sides.
The intense fighting, which started more than two weeks ago, triggered an exodus of tens of thousands of Sudanese to neighboring countries including Egypt, Chad and the Central African Republic.
The UN’s Humanitarian Coordinator in Sudan Abdou Dieng said the conflict was turning into a full blown catastrophe
More than 500 people have been reported killed since fighting erupted on April 15 between Sudan’s army chief Abdel Fattah al-Burhan and Mohamed Hamdan Dagalo, who commands the paramilitary Rapid Support Forces.
Millions of Sudanese around the capital and beyond have sheltered in their homes with dwindling food and water and frequent power cuts, as fighter jets thundering through the sky on bombing raids have drawn heavy anti-aircraft fire.
“Warplanes are flying over southern Khartoum and anti-aircraft guns are firing at them,” said one resident, while another witness told AFP he was also hearing “loud gunfire”.
