Sudan’s military has dissolved civilian rule, arrested political leaders and declared a state of emergency.
Gen Abdel Fattah Burhan, who had been heading a joint council with civilian leaders, blamed political infighting.
Protesters have taken to the streets of the capital, Khartoum, and there are reports of gunfire.
Military and civilian leaders have been at odds since long-time ruler Omar al-Bashir was overthrown two years ago and a transitional government set up.
Although the country remains in a deep economic crisis, there has been more international support and a military takeover will put that hugely at risk.
Prime Minister Abdallah Hamdok is among those reported to have been put under house arrest, along with members of his cabinet and other civilian leaders.
