Members of Sudan’s transitional government and other civilian leaders have been arrested amid reports of a military coup.
Prime Minister Abdallah Hamdok is among those reported to have been put under house arrest by unidentified soldiers.
The army has not commented, but pro-democracy groups urged street protests.
Military and civilian leaders have been at odds since long-time ruler Omar al-Bashir was overthrown two years ago and the transitional government set up.
It remains unclear who was behind the pre-dawn arrests.
A statement from the information ministry on Facebook said the detentions were carried out by “joint military forces” and those arrested were being held in “an unidentified location”.
The ministry said soldiers had stormed the HQ of the state broadcaster in Omdurman and detained staff there.
It also said Mr Hamdok was being pressed to support a coup but was refusing to do so and he urged people to continue with peaceful protests to “defend the revolution”.
The United States was “deeply alarmed” by the coup reports, its special envoy for the Horn of Africa, Jeffrey Feltman, said.
Witnesses have said that the internet is down in the north African nation’s capital, Khartoum, while images have appeared on social media showing angry crowds burning tyres in the streets.
The army and paramilitary have been deployed across the city, restricting the movement of civilians, a witness is quoted as saying by Reuters news agency.
Khartoum airport is now closed, and international flights are suspended.
Sudan’s main pro-democracy group has called on its supporters to resist any military coup.
The military and civilian transitional authorities have ruled together since President Bashir was toppled after months of street protests in 2019.
