OUAGADOUGOU, Burkina Faso — Six people, including a pastor, were killed in an attack on a Christian church in Burkina Faso, a government spokesman said.

The violence took place Sunday in the village of Silgadji, in the country’s north, not far from the volatile border with Mali.

Urbain Kabore, the communications director for the Sahel region of Burkina Faso, said Monday that the six people were killed after Sunday services.

There was no immediate claim of responsibility.

Violent Islamist extremism has been increasingly destabilizing Burkina Faso, and a number of jihadist groups are known to operate in the area of the attack.
