Sudanese authorities reported a coup attempt on Tuesday by a group of soldiers but said the attempt failed and that the military remains in control.
Sudan's state-run television called on the public "to counter" the attempt but did not provide further details.
"All is under control. The revolution is victorious," Mohammed al-Fiky Suliman, a member of the ruling military-civilian council, wrote on Facebook. He also called on the Sudanese to protect the transition.
A military official said an unspecified number of troops from the armoured corps were behind the attempt and that they tried to take over several government institutions but were stopped in their tracks.
The official, who spoke on condition of anonymity because he was not authorized to brief the media, said many troops, including high-ranking officers, have been arrested. He did not provide further details, saying that a military statement would be released shortly.
Sudan has been on a fragile path to democratic rule since the military's ouster of the country's longtime autocratic ruler Omar al-Bashir in April 2019, following four months of mass protests.
The country is now ruled by a joint civilian and military government that faces towering economic and security challenges.
