In 2019 April Omar Al-Bashir, who was the leader of Sudan for three decades, was removed by a coup d'etat. In the following month a military-civilian joint government took over, with the promise of an election in 2023. Abdalla Hamdok became the PM (who served in various positions in the bureaucracy, was a minister too).
Now the military faction took the civilian leaders into custody (including Hamdok), monopolizing the power for themselves. There were some protests demanding each side to take over, essentially.
Additional information:
- before Al-Bashir was deposed by the armed forces, protesters also demanded them doing something.
- in September a coup attempt was done by the military, they just botched it
- internationally the coup was condemned and everyone expressed their deepest concern as usual
