The latest unrest began on Friday, when junior military officers announced they had toppled the country's junta leader, sparking deep concern among world powers over the latest putsch to hit the Sahel region battling a growing Islamist insurgency.

Late on Saturday, the junta leader, Paul-Henri Sandaogo Damiba, said he had no intention of giving up power and urged the officers to "come to their senses".

His comments came shortly after the army general staff dismissed the coup as an "internal crisis" within the military and said dialogue was "ongoing" to remedy the situation.

The capital remained tense overnight, with demonstrators gathering on the main roads of Ouagadougou as a helicopter hovered above.

In a statement read out on television on Sunday, the officers who claimed the coup said they had lifted a curfew they had imposed and called for a meeting of ministry heads for later in the day.

The officers had accused Damiba of having hidden at a military base of former colonial power France to plot a "counteroffensive," charges that he and France denied.

On Sunday, dozens of supporters of the new self-proclaimed putsch leader, Ibrahim Traore, gathered at the French embassy in the capital.

Security forces fired tear gas from inside the compound to disperse the protesters after they set fire to barriers outside and lobbed rocks at the structure, with some trying to scale the fence, according to an AFP reporter on the scene.

There were no immediate reports of injuries.

The French foreign ministry condemned "the violence against our embassy in the strongest terms" by "hostile demonstrators manipulated by a disinformation campaign against us."

It marked the latest incident against a France-linked building in two days, after a fire at the embassy on Saturday and a blaze in front of the French Institute in the western city of Bobo-Dioulasso. A French institute in the capital also sustained major damage, the foreign ministry said.

Traore called for an end to the attacks on Sunday.

"Things are progressively returning to order, so we urge you to freely go about your business and to refrain from any act of violence and vandalism... notably those that could be perpetrated against the French embassy and the French military base," an officer said, reading a statement on television from Traore, who stood by his side.

The officers said they had carried out their putsch because Damiba had failed to quell jihadist attacks in the country.

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

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

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

- 'Burkina Faso needs peace' -

Friday's coup claim sparked a wave of international criticism, including from the United States, the African Union, the European Union and the regional grouping ECOWAS.

"Burkina Faso needs peace, stability and unity to fight terrorist groups and criminal networks operating in parts of the country," said a statement by UN Secretary General Antonio Guterres.

Jihadist violence has also prompted a series of coups in Mali, Guinea and Chad since 2020.

The new Burkina 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.

A few hours before the coup on Friday, hundreds of people had rallied in the capital seeking Damiba's departure, the end of France's military presence in the Sahel and military cooperation with Russia.

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