The officers claimed to have toppled Damiba on Friday, saying he had failed to quell jihadist attacks. It is the second coup this year in the West African country.

Making his first comments since the putsch, Damiba in a written statement urged his rivals "to come to their senses to avoid a fratricidal war that Burkina Faso doesn't need".

He rejected allegations by the army officers who seized power that he was hiding in a French base, but provided no further details about his location.

Damiba himself came to power in a coup in January. He installed himself as leader of the country of 16 million after accusing elected president Roch Marc Christian Kabore of failing to beat back jihadist fighters. But the insurgency has raged on.

The junior officers had said in televised comments that Damiba was planning a counteroffensive from a "French base".

Damiba "is believed to have taken refuge in the French base at Kamboinsin in order to plan a counter-offensive to stir up trouble in our defence and security forces," they said in a statement read out on national television and signed by Captain Ibrahim Traore, the country's new strongman.

In his comments on the presidency's official Facebook page, Damiba called that claim an attempt "to manipulate opinion".

France, the former colonial power in Burkina Faso, via its embassy earlier in the day also denied "any involvement of the French army in the events of the last few hours".

It denied "rumours that Burkinabe authorities have been hosted or are under the protection of the French military" personnel.

The general staff of Burkina Faso's army dismissed the coup as an "internal crisis" within the military, and said dialogue was "ongoing" to remedy the situation.

- 'Burkina Faso needs peace' -

Among a wave of international condemnation, UN Secretary General Antonio Guterres "strongly condemns any attempt to seize power by the force of arms and calls on all actors to refrain from violence and seek dialogue," his spokesman said.

"Burkina Faso needs peace, stability and unity to fight terrorist groups and criminal networks operating in parts of the country," the UN statement added.

With much of the Sahel region battling a growing Islamist insurgency, the violence has prompted a series of coups in Mali, Guinea and Chad since 2020.

The new Burkina Faso putschists said they were willing "to go to other partners ready to help in the fight against terrorism".

No country was explicitly mentioned but Russia, whose influence is growing in French-speaking Africa, is among the possible partners in question.

France has a military presence in Burkina Faso, with a contingent of special forces based in Kamboinsin which is about 30 kilometres (19 miles) from the capital Ouagadougou.

- Gunfire, helicopters -

The situation in the capital Ouagadougou was tense on Saturday, with gunfire and soldiers deployed in the streets.

Helicopters hovered above the city and shops shut their doors.

Late Saturday a French government spokeswoman strongly condemned "violence" against its embassy, after an AFP reporter said he saw a fire burning outside the building in Ouagadougou in the afternoon.

Witnesses said a fire also broke out in front of the French Institute in the western city of Bobo-Dioulasso.

African Union chief Moussa Faki Mahamat condemned the "unconstitutional change of government" in Burkina Faso, calling for the restoration of the constitutional order by July 2024.

The European Union warned the latest coup put in danger efforts towards restoring constitutional order by that same date, while the US government said it was "deeply concerned".

- Damiba accused of failure -

Just before 8:00 pm (2000 GMT) on Friday, more than a dozen soldiers in fatigues appeared on the state television and radio broadcaster to announce the removal of Damiba.

They proclaimed 34-year-old Captain Traore in charge. He was previously head of anti-jihadist special forces unit "Cobra" in the northern region of Kaya.

"Damiba failed," said Habibata Rouamba, a trader and activist.

"Since he came to power, the zones that were peaceful were attacked. He took power but then he betrayed us," he said.

The new leaders suspended the constitution, sealed the borders, dissolved the transitional government and legislative assembly and instituted a 9:00 pm to 5:00 am curfew.

More than 40 percent of Burkina Faso remains outside government control.

In the north and east, towns have been blockaded by insurgents who have blown up bridges and attacked supply convoys.

As in bordering countries, insurgents affiliated with Al-Qaeda and the Islamic State group have stoked unrest.

Thousands have died and about two million have been displaced by the fighting since 2015 when the insurgency spread to Burkina Faso.
