At least 14 people were shot dead after unknown gunmen opened fire inside a church in eastern Burkina Faso on Sunday morning.
The incident happened during hours of worship at the church in the village of Hantoukoura, near the border with Niger.
A statement from the regional government said that many people are injured.
The identity of the gunmen was not immediately clear and further details on the attack had yet to emerge. However, the area where the attack took place is known for banditry and has come under frequent attacks from suspected jihadist groups with links to al Qaeda and Islamic State.
Hundreds of people have been killed in Burkina Faso over the past few years, mostly by jihadist groups, sparking ethnic and religious tensions especially on the border with Mali.
Last October, 15 people were killed and two seriously injured in an attack on a mosque.
