OUAGADOUGOU, Burkina Faso — Gunmen killed a pastor and five congregants at a Roman Catholic church in northern Burkina Faso on Sunday, the authorities said, in the second attack on Christians in two weeks in a nation increasingly overrun by jihadists.

Congregants were leaving the church around 9 a.m. local time in the town of Dablo, about 124 miles from the capital, Ouagadougou, when about 20 men circled them and opened fire, leaving at least six dead, according to a government statement.

“These terrorist groups are now attacking religion with the macabre aim of dividing us,” the statement said.

The mayor of Dablo said the attackers burned the church, looted a pharmacy and some others stores and left. A government spokesman said the gunmen also destroyed all places serving alcohol.
