[1/4] People gather at the station to flee from Khartoum during clashes between the paramilitary Rapid Support Forces and the army in Khartoum, Sudan April 19, 2023.
Guterres and senior officials from the U.S., Saudi Arabia, Qatar, Turkey and Egypt called Sudan's army chief General Abdel Fattah al-Burhan to urge an end to violence.
Urging a three-day ceasefire, he said civilians trapped in conflict zones should be allowed to escape and to seek medical treatment, food and other supplies.
Witnesses in the city of El-Obeid, east of Darfur, described clashes between the army and RSF troops and widespread looting.
Many other local people remain trapped, along with thousands of foreigners in a city that has become a war zone.
