According to the Ministry of the Interior, the victims of the attack near the Mali border included nine people working in the fields.
The government stated that armed men on motorcycles launched attacks near the turbulent border between western Niger and Mali, killing at least 14 civilians.
The attack took place around 3 pm on Sunday (14:00 GMT) when the unidentified attacker arrived in the village of Vie, in the Banibangu district, about 50 kilometers (30 miles) from the Mali border.
The Ministry of the Interior said in a statement on state television on Monday that they “targeted civilians and killed 14 people, 9 of whom were working in the fields.”
It added that an injured person had been transferred to the capital Niamey for treatment.
It said that security measures have been strengthened and investigations are ongoing to identify those responsible for “these cowardly and brutal attacks” and bring them to justice.
So far, no one has claimed responsibility.
Banibangou is located on the three borders between Niger, Burkina Faso and Mali. It has been the site of bloody attacks by armed groups associated with Al-Qaida and ISIL for many years.
The previous attack in the Tillabury area of western Niger was blamed by local officials on an affiliate of ISIL, including the January attack that killed at least 100 civilians.
In mid-March, an attack on a rural market in the same area killed 66 people, and on June 24, a village in the neighboring area Todikiwindi was attacked, killing 19 people.
Despite repeated efforts by the authorities to ensure the safety of the area, violence continued, usually with gunmen on motorcycles who fled across the border to Mali after the attack.
As part of the multinational force formed by the G5 Sahel group composed of Burkina Faso, Chad, Mali, Mauritania and Niger, a task force of 1,200 Chadian soldiers is deployed in three border areas.
