The attack took place in the small town of Dablo, about 200 kilometres north of the capital, Ouagadougou, in Burkina Faso, Africa.
The faithful were leaving church after the 9 AM Mass, when about 20 suspected jihadists on motorcycles encircled the church.
From reports by eyewitnesses, it appears that their target was the 34-year old Burkinabe priest, Father Simeon Yampa, in charge of interreligious dialogue in his diocese. When he tried to escape, the terrorists chased and killed him.
Returning to the church, they forced the faithful to lie on the ground, picked out five of them and shot them.
Dablo mayor, Ousmane Zongo, told Reuters the attackers then burned the church, looted a pharmacy and some other stores, and left.
No one has claimed responsibility but the attacks bore the hallmarks of Islamic extremists who are known to be active in the area.
“The Holy Father has learned with sorrow about the news of the attack on the church in Dablo, Burkina Faso. He prays for the victims, for their families and for the entire Christian community in the country," said a spokesperson for the Vatican.
