On early 10 April 2024, Ambazonian separatist rebels of the Bui Unity Warriors attacked the base of the Cameroonian Rapid Intervention Battalion in Kumbo, resulting a battle that lasted for hours.

After the beginning of the Anglophone Crisis, Ambazonian rebels began to operate in the Northwest Region's department Bui whose center is Kumbo.

The separatists enjoyed some advantage in the area as its mountainous terrain and poor infrastructure made it difficult for the security forces to clear them out.
