Last week, the Defence Headquarters announced the emergence of Lakurawa as a new terror group operating in Sokoto and Kebbi states.
Lagbaja served as the Chief of Army Staff for one year and four months. President Tinubu appointed him to the role in June 2023.
The incident happened in the early hours of the day but the cause of the explosion is still unknown as of now.
The mayor of the town, Volga Ramirez Gamiz, told reporters that the fire was concentrated in one room, but the smoke spread throughout the residence.
The suit, which was initially instituted by attorneys general of 16 states, sought the scrapping of the anti-graft agency.
