The soldiers who ousted Mali’s President Ibrahim Boubacar Keïta say they plan to set up a civilian transitional government and hold new elections.
The spokesman for the soldiers said they acted to prevent the country falling further into chaos.
President Keïta resigned on Tuesday night saying he did not want “blood to be spilled to keep me in power.”
The African Union, regional leaders, and the UN have condemned the coup.
South Africa’s President Cyril Ramaphosa, the current African Union (AU) chairperson, urged the soldiers to release President Keïta and others government officials being detained.
The UN Security Council is to hold an emergency session on Wednesday to discuss the latest developments.
Mali, a vast country stretching into the Sahara Desert is among the poorest countries in the world and has experienced several military takeovers. It is currently battling to contain a wave of jihadist attacks and ethnic violence.
