In a phone conversation with Sky News Arabia, South Sudanese foreign minister Deng Dau added that Kiir called on Sudan's Army chief, Gen. Abdel Fattah al-Burhan and RSF commander Mohammed Hamdan Dagalo, Known as Hamidti, for a ceasefire, stressing that he is ready to visit Khartoum any time.

Gen. Abdel Fattah al-Burhan confirmed that he received an invitation from The Intergovernmental Authority on Development (IGAD) to send a military delegation to Juba for negotiations with the leader of RSF to reach a peaceful solution to the current conflict in Sudan.

Deng Dau added that President Kiir contacted both Burhan and Hamidti to hold a meeting in Sudan or outside to put an end to this war.

Sudan's army chief accepted the IGAD invitation, but South Sudanese officials are still trying to communicate with Hamidti for a possible meeting with al-Burhan.

At least 512 people, including civilians and combatants, have been killed in Sudan since April 15, with another 4,200 wounded, according to the Sudanese Health Ministry.

The Doctors’ Syndicate, which tracks civilian casualties, has recorded at least 295 civilians killed and 1,790 wounded.

The 72-hour cease-fire announced by US Secretary of State Antony Blinken was to last until late Thursday night.

Many fear that fighting will only escalate once evacuations of foreigners, which appeared to be in their last stages, are completed.
