Sudan's Army Chief General Abdel Fattah al-Burhan was seen Thursday outside his headquarters for the first time since fighting erupted more than four months ago with paramilitaries.

Some of the footage filmed before dawn and posted on the army's Facebook page showed Burhan speaking to soldiers, with the caption indicating that he was at the Wadi Seidna air base north of Khartoum.

In separate daytime images posted later, he was seen surrounded by civilians in the capital's twin-city of Omdurman.

Images of Burhan have rarely been released since fighting erupted on April 15 between the army and the paramilitary Rapid Support Forces (RSF) of his former deputy Mohamed Hamdan Daglo.

Previous images showed Burhan inside the army headquarters in Khartoum, over which both sides have waged fierce battles to control.

The latest footage comes as fighting rages around a key military base in the capital's south.

The army has put out several statements and videos saying it has repelled RSF attacks since Sunday against Al-Shajara base but the paramilitaries claim they have taken control of much of it since Wednesday.

Also on Wednesday, the RSF said 2,500 fighters from a movement led by former rebel leader Malak Agar, recently named by Burhan as his deputy to replace Daglo, had pledged allegiance to the paramilitaries.

Access24 reports that according to United Nations figures, in the four months since the fighting broke out, more than 4.6 million people have been forced to flee their homes.
