The Nigerian government has announced a new military operation to tackle Islamic militants after more than 160 people were killed in western Kwara state. Local officials said the attack occurred Tuesday in the villages of Woro and Nuku. Amnesty International called it “a stunning security failure.” No group has claimed responsibility, but locals suspect Islamic militant groups. Kwara has seen a rise in violence, with experts warning it’s becoming a new frontier for armed groups seeking to expand. President Bola Tinubu’s office announced late Wednesday that a Nigerian army battalion will be deployed to the area.
