Security forces in Benin are searching for the soldiers who tried to seize power on Sunday morning, with the president saying they have taken an unknown number of hostages.
The coup plotters appeared on state TV to announce they had taken over, and gunfire was heard near the presidential residence.
However, President Patrice Talon later announced that the situation was totally under control in the West African country.
Regional power Nigeria assisted in thwarting the mutiny, saying its fighter jets had helped dislodge the coup plotters from the National TV and a military camp following a request from Benin's government.
On Sunday afternoon, huge explosions were heard in Cotonou, Benin's largest city and seat of government. They were thought to have been the result of an air strike.
Prior to the explosions, flight-tracking data showed that three aircraft had entered Benin's airspace from neighbouring Nigeria before returning home. The extent of the damage is not clear.
Earlier on Sunday, Benin government spokesperson Wilfried Leandre Houngbedji told the Reuters news agency that 14 people had been arrested in connection with the attempted coup.
A journalist in Benin also told the BBC that of those reportedly arrested, 12 are believed to have stormed the offices of the national TV station - including a soldier who had previously been sacked.
The coup plotters said they were led by Lt Col Pascal Tigri, whose whereabouts are not known.
In Sunday evening's national address, the 67-year-old president said that loyalist forces had cleared the last pockets of resistance held by the mutineers.
This commitment and mobilisation enabled us to defeat these opportunists and avert disaster for our country. This treachery will not go unpunished, he added.
I would like to reassure you that the situation is completely under control and therefore invite you to go about your business peacefully.
It is not clear if there have been any casualties, but the president expressed his condolences to the victims of this senseless adventure, as well as to those still being held by fleeing mutineers.
There had been a series of coups in West Africa before Sunday's thwarted attempt in Benin, heightening fears that the security of the region could worsen.
Benin, a former French colony, has been regarded as one of Africa's more stable democracies. But Talon has faced accusations of suppressing criticism of his policies.
The nation is one of the continent's largest cotton producers, but ranks among the world's poorest countries.
Nigeria, Benin's large neighbour to the east, has described the coup attempt as a direct assault on democracy.
