A plot to kill Burkina Faso's military leader, Capt Ibrahim Traoré, has been thwarted, the West African nation has announced.

The sophisticated plan had been hatched by Lt Col Paul Henri Damiba, the military officer ousted by Traoré in September 2022, the security minister said in a late-night broadcast.

"Our intelligence services intercepted this operation in the final hours. They had planned to assassinate the head of state and then strike other key institutions, including civilian personalities," said Mahamadou Sana, further alleging that the plot had been funded from neighbouring Ivory Coast.

There has been no comment from either Col Damiba or Ivory Coast.

Since seizing power, Capt Traoré has faced at least two coup attempts and is also grappling with growing jihadist violence that has forced millions from their homes.

Despite these challenges and his authoritarian reputation, the 37-year-old military leader maintains strong popular support and has gained a following across the continent for his pan-Africanist vision and criticism of Western influence.

According to the security minister, the authorities uncovered a leaked video showing the plotters discussing their plans.

In the footage they allegedly spoke about how they intended to assassinate the president - either at close range or by planting explosives at his residence - just after 23:00 local time on Saturday 3 January.

Afterwards they allegedly planned to target other senior military and civilian figures.

Sana alleged that Damiba had mobilised both soldiers and civilian supporters, secured foreign funding - most significantly 70m CFA francs ($125,000; £92,000) delivered from Ivory Coast - and planned to knock out the country's drone-launch base before foreign forces could intervene.

"We are carrying out ongoing investigations and have made several arrests. These individuals will be brought to justice soon," the minister said on national television.

Sana insisted the situation was under control and urged citizens "not to be misled, out of naivety, into dangerous schemes".

It is not clear how many people have been arrested.

Critics, both local and foreign, have accused Traoré of authoritarianism and say his government suppresses dissent - including arbitrary arrests of military officers and restrictions on the media.

It is not the first time the junta has pointed the finger of blame about foreign interference in its affairs at Ivory Coast.

These continuing internal power struggles will further heighten regional tensions.

Col Damiba served as Burkina Faso's leader from January-September 2022 after seizing power from an elected government.

After being ousted he went into exile in neighbouring Togo and said in a message published on social media that he wished his successor every success.
