This was confirmed on Tuesday in a tweet from presidential media aide, Femi Adesina in which he also quoted the president as appreciating the outgone service chiefs for their performance.
Recall that the former service chiefs were appointed in July 2015, barely two months after assuming office.
They were Chief of Defence Staff, General Abayomi Olonisakin; Chief of Army Staff, Lt-Gen. Tukur Buratai; Chief of Naval Staff, Vice Admiral Ibok Ekwe Ibas; Chief of Air Staff, Air Marshal Sadique Abubakar.
The replacements are Major-General Leo Irabor, Chief of Defence Staff; Major-General I. Attahiru, Chief of Army Staff; Rear Admiral A. Z. Gambo, Chief of Naval Staff; Air-Vice Marshal I. O. Amao, Chief of Air Staff.
Military personnel in a video were seen dancing, while they fire shots in celebration of the removal of the former security heads.
