The United Nations has joined global condemnation of the military takeover in Mali, which saw President Ibrahim Boubacar Keïta forced to resign.
The UN's Security Council echoed similar calls by regional bodies for the immediate release of all government officials and the restoration of constitutional order.
The soldiers said they acted to prevent the country falling into further chaos.
They say they will set up a civilian government and hold new elections.
Mali, a vast country stretching into the Sahara Desert, is among the poorest in the world and has experienced several military takeovers. It is currently battling to contain a wave of jihadist attacks and ethnic violence.
Mr Keïta won a second term in elections in 2018, but since June has faced huge street protests over corruption, the mismanagement of the economy and disputed legislative elections.
There has also been anger among troops about pay and the conflict with jihadists.
The African Union earlier suspended Mali, saying military coups were "something of the past which we cannot accept anymore".
"Whenever you have a crisis and the military people have a coup and say 'we are responding to the will of the people', this way of responding is not acceptable at all," the AU's Commissioner for Peace and Security, Smail Chergui, told the BBC's Focus on Africa programme.
The 15-member Economic Community of West African States (Ecowas) has also taken swift action against Mali – closing borders, suspending financial flows and ejecting it from decision-making bodies.
US Secretary of State Mike Pompeo tweeted his condemnation, and French President Emmanuel Macron urged a return to civilian rule saying "the fight against terrorist groups and the defence of democracy and the rule of law are inseparable".
The U.S. strongly condemns the August 18 mutiny in Mali. We join our international partners including the Economic Community of West African States and the @_AfricanUnion in denouncing these actions.

Who are the coup leaders?
Reports in Mali say Colonel Assimi Goita has been confirmed as president of the new military junta, which is calling itself the National Committee for the Salvation of the People (CNSP).
He met senior civil servants earlier on Wednesday and told them: "We have no political ambitions, we are soldiers, our objective is to rapidly transfer power. The state will continue, we assure you of our support in order to work in tranquillity, we want to reassure you," the Malian newspaper Journal du Mali reports.
Other members of the junta identified in the report include Col Malick Diaw, CNSP vice-president, and Col Ismaël Wagué, the air force deputy chief of staff, who had earlier read a statement on behalf of the group.
The newspaper quotes local websites as saying four civilians were killed by gunfire during the military takeover, although this has been denied by coup leaders.
In another development, the head of the Mali's opposition M5 movement, conservative Imam Mahmoud Dicko, announced he would be withdrawing from politics after meeting with the coup leaders. No reasons were given.
Mr Dicko has called for reforms after rejecting concessions from Mr Keïta.
