President Muhammadu Buhari on Friday met behind closed with the Chief of Defence Staff, Gen. Gabriel Olonisakin, at the Presidential Villa, Abuja.
The Secretary to the Government of the Federation, Boss Mustapha, also attended the meeting.
The meeting may not be unconnected with the killing of five Nigerian soldiers in an ambush along the Maiduguri-Damaturu highway on Wednesday.
The Army in a statement had confirmed that a colonel, a captain and three soldiers were killed in an ambush by Boko Haram terrorists.
