More than 10 soldiers have been killed by suspected jihadists in Burkina Faso's eastern region, military sources have said.
It followed Sunday's attack on a military patrol and security team in Natiaboni, a rural town in an area that has been regularly targeted by attackers.
Burkina Faso's military government seized power in January and ousted President Roch Kaboré, blaming him for failing to tackle a jihadist insurgency.
The violence since 2015 has left thousands dead and forced millions to flee their homes.
