The president of the West African nation of Burkina Faso confirmed that 14 people died in an attack on a Protestant church during Sunday services in the east of the country.
President Roch Marc Christian Kabore said on Twitter that he condemned "the barbaric attack,quot; in the city of Hantoukoura. He said several people were also injured.
Kabore offered his "deepest condolences to the bereaved families,quot; and wished "a speedy recovery to the wounded."
The identity of the gunmen was not immediately clear and no further details about the attack had been revealed. Burkinabe armed forces were taking care of the injured and searching the area, the government said in a statement.
Until 2015, the poor country in West Africa largely escaped the violence that hit Mali and then Niger, its northern neighbors.
But the attackers, some linked to al Qaeda, others to the Islamic State from the group of Iraq and the Levant (ISIL or ISIS) – began to infiltrate the north, before moving east and towards the south and west borders.
The riots have caused ethnic and religious tensions, making much of the country ungovernable.
The attack took place in the village of Hantoukoura, near the border with Niger in the Eastern region, an area known for banditry that has been attacked over the past year by groups with alleged links to al-Qaeda and ISIL.
The time of the last incident, during the hours of worship, reflected other attacks against Christians this year, a new phenomenon in a West African country that has taken pride in its religious tolerance.
Hundreds have been killed during the past year and almost one million have been forced to leave their homes.
