Eleven soldiers have died and 50 civilians are missing in Burkina Faso following a suspected jihadist attack, the government says.
A supply convoy escorted by the army travelling to the northern town of Djibo was targeted in an ambush on Monday.
The government called it a “barbaric attack”, the AFP news agency says.
The region is facing a jihadist crisis that has killed thousands and displaced more than two million.
The military, led by Lt Col Paul-Henri Sandaogo Damiba, took power in a January coup, promising an end to the Islamist insurgency that started in 2015, but violence still rages.
Lt Col Damiba had been at the forefront of the country’s fight against Islamist militants and even wrote a book on the subject last year called West African Armies and Terrorism: Uncertain Responses?
