At least seven people were killed in unrest triggered by the military takeover, which brought a halt to Sudan's transition to democracy two years after a popular uprising ended decades of authoritarian rule.
Plumes of smoke rose over Khartoum from tyres set ablaze by protesters. Life came to a halt in the capital and in its twin city Omdurman across the Nile, with roads blocked either by soldiers or by protester barricades.
The night appeared to have passed comparatively quietly after Monday's unrest, when protesters took to the streets after soldiers arrested Prime Minister Abdalla Hamdok and other civilians in the cabinet. A health ministry official said seven people had been killed in clashes between protesters and the security forces.
On Monday, General Abdel Fattah al-Burhan dissolved the military-civilian Sovereign Council, and announced a state of emergency, saying the armed forces needed to protect safety and security. He promised to hold elections in July 2023 and hand over to an elected civilian government then. On Tuesday he dissolved committees that govern trade unions, Arabic news channels reported.
