Amnesty International has called on the Nigerian government to urgently investigate a deadly attack that claimed 15 lives in Plateau State.

The human rights group said gunmen stormed several villages in Chakfem, Mangu Local Government Area, on Monday evening.

The affected villages include Tim, Koppang, Mihidihin, Jiblang, Jilem, Jibin and Manden.

According to eyewitnesses, the attackers killed people they encountered and also set fire to homes and other properties. More than 200 residents were forced to flee their communities.

Amnesty International described the incident as another example of how rural communities in Plateau remain exposed to repeated, violent raids. It accused Nigerian authorities of failing to protect citizens from what it called “rampaging gunmen.”

“Failure to stop these attacks is costing people their lives and livelihoods. Without immediate action, many more lives may be lost,” the group warned.

The organisation recalled that between December 2023 and February 2024, at least 1,336 people were killed in Plateau, including 533 women and 263 children.

In the same period, 29,554 people were displaced. Earlier in April 2025, at least 51 people were killed in a separate attack in Bassa Local Government Area.
