Sudan's prime minister has replaced four key ministers after protests over the slow pace of reform following the overthrow of Omar al-Bashir as president last year.

Abdalla Hamdok dismissed the health minister and accepted the resignations of the three others - in charge of finance, foreign affairs, and energy, the government said.

Correspondents say the Sudanese economy was already in a crisis before the impact of the coronavirus so the new finance minister faces a daunting task amid worsening food and fuel shortages.

On Sunday Mr Hamdok - who heads a power-sharing interim government with the military - replaced the police chief and his deputy.
