Fourteen students were killed on Saturday morning in Toeni, in Burkina Faso’s northwestern province of Sourou, after the bus they were traveling in plunged into a mine, Xinhua reports citing a security source.

An army official, who spoke on condition of anonymity, said that four other people were injured in the incident.

According to the official, the bus was traveling to the city of Toma, the capital of Nayala Province.

The cause of the accident has not yet been established.

Road accidents claim the lives of tens of people and leave hundreds of people injured every day in Burkina Faso, according to health authorities.

In the capital, Ouagadougou, police recorded 1,700 road accidents, or at least 20 accidents per day, over the first quarter of 2017.

In that year in May, 18 people were killed while four others injured after a public transport car and a vehicle transporting goods collided within Tambi Park near the southern city of Po.

Burkina Faso is already struggling with an Islamist insurgency which recently saw 38 people killed after a bus convoy of mineworkers was attacked.
