Sudan's Prime Minister Abdalla Hamdok has sacked the governor of the capital, Khartoum, after he opposed a ban on religious gatherings imposed to try to curb the spread of Covid-19.

General Ahmed Abdun Hammad Mohammed refused to implement a decision to ban prayers in mosques and churches due to come into force on Saturday.

Earlier on Thursday, police fired teargas at supporters of the ousted President Omar al-Bashir.

They were demonstrating against the transitional government's austerity programme.
