At least fifty-three members of the security forces have been killed in an attack by suspected militants in northern Burkina Faso, the army said.

Seventeen soldiers and 36 civilian volunteers for the army died on Monday while repelling an "attack," the army general staff said in a statement on Tuesday.

The unit had been deployed in the town of Koumbri in Yatenga province to help the resettlement of residents forced out of the area by militants more than two years ago, it said.

About 30 members of the security forces were injured, the army added.

It said that several attackers had been "neutralised" in a counter-operation and their combat equipment destroyed.

Operations are still under way in the area, it said.

Burkina Faso saw two military coups last year, triggered - as in neighbouring Mali and Niger - by anger at failures to stem a militant insurgency that has claimed thousands of lives.

Since 2015, more than 16,000 civilians, troops and police have died in militant attacks in Burkina Faso, according to a count by an NGO monitor called the Armed Conflict Location & Event Data Project (ACLED).

More than 5,000 have died since the start of this year.

More than two million people have also been displaced within Burkina Faso, making it one of the worst internal displacement crises in Africa.

Other attacks

On June 26, three attacks killed 31 soldiers and 40 auxiliaries in Centre-North province.

In August, two attacks in Centre-East province killed five police and around 20 others.

The authorities, for their part, say more than 65 militants were "neutralised" between August 7 and September 1.

The country's strongman is Captain Ibrahim Traore, who took power in September 2022 at the age of just 34, making him the world's youngest leader outside of royalty.

He has promised a return to democracy with presidential elections by July 2024.

Relations between the junta and France broke down after the takeover, prompting French forces that had been helping the under-equipped Burkinabe army to quit the country in January.

Traore last week held talks with a Russian delegation on development and military cooperation.

On Monday, his foreign minister, Olivia Rouamba, held talks in Tehran with President Ebrahim Raissi in which she said she hoped for "stronger bilateral cooperation" with Iran.

Many of the casualties among the security sources are Volunteers for the Defence of the Fatherland (VDP) - civilians who are given two weeks of military training and work alongside the army, typically carrying out surveillance, information-gathering or escort duties.
