"Unfortunately the situation remains grave in Sudan.

"I invite everyone to pray for our Sudanese brothers and sisters," he added.

Ferocious battles between the Sudanese army and a paramilitary group -- which has seen fighting with tanks in densely populated Khartoum and air strikes launched by fighter jets -- have killed more than 400 people and left thousands wounded.
The fighting between army chief Abdel Fattah al-Burhan's forces and the rival Rapid Support Forces (RSF) of his former deputy Mohamed Hamdan Daglo began on April 15 over a dispute on the planned integration of the RSF into the regular army.
The move was a key condition of a deal aimed at restoring Sudan's democratic transition after the military toppled former leader Omar al-Bashir in April 2019 following mass citizen protests.
The two men had joined forces to oust a civilian government installed after Bashir's downfall, before turning on each other.
