Gunmen burst into a church in northern Burkina Faso on Sunday and fatally shot four people, a security source said. It was at least the fourth attack on Christians in the West African country in the past month.
Other worshipers were wounded by the gunfire at the morning service at the church near the town of Titao, the source added.
No one has claimed responsibility for the attacks, which threaten to upend traditionally peaceful relations between the Muslim majority and Christians who make up a quarter of the country’s people.
The government has blamed unnamed terrorist groups operating in the country and Africa’s surrounding Sahel region.
Islamist militants based in Mali, to the north, have regrouped since a French intervention in 2013 and now use it as a launching pad for attacks on Burkina Faso and neighboring Niger.
In late April gunmen killed a Protestant pastor and five congregants in another church in northern Burkina. A Catholic priest and five parishioners were killed, and their church burned, in the central town of Dablo on May 12, and four other Catholics died in an attack two days later in the northern town of Ouahigouya.
