One of the poorest countries in the world, Burkina Faso is struggling with a ruthless insurgency by armed Islamists who swept in from neighbouring Mali in 2015.

Almost 1,100 people have died and more than a million people have fled their homes.

French Tigre helicopters on Saturday "neutralised" a "suspicious convoy of 30 motorcycles" on Burkinabe territory near the Mali town of Boulikessi in which some 10 jihadists were killed, said Colonel Frederic Barbry, spokesman for the French defence staff.

The same day, a French drone struck a four-wheel drive vehicle heading for Mali, he said.

On Sunday, French helicopters fired on a convoy of 40 motorbikes "allowing us to stop the convoy and neutralise more than 10 armed terrorists and destroy about 10 motorbikes," Barbry added.

France has deployed troops in the region to fight jihadists.
