Sudanese authorities now say they have foiled an attempted coup, accusing plotters loyal to ousted president Omar al-Bashir of a failed bid to derail the 2019 revolution.
Two years ago, a military-led coup ended 30 years of autocratic rule under Mr Bashir and ushered in a transition to democracy.
Announcing early on Wednesday that the coup had failed, the Sudanese military said 21 officers and a number of soldiers had been detained in connection to the attempted take-over. It said in a statement that a search was underway for others.
All affected locations were under army control, it said.
Analysts say the coup attempt points to the difficult path facing a government that has reoriented Sudan since 2019, winning Western debt relief and taking steps to normalise ties with Israel. They also credit the government with tackling a severe economic crisis.
Since Mr Bashir’s overthrow, a ruling body known as the Sovereign Council has been running the north African nation under a fragile power-sharing deal between the military and civilians.
Elections are due in 2024.
Mr Bashir, the intended beneficiary of the attempted coup, is wanted by the International Criminal Court over alleged atrocities in Darfur in the early 2000s.
