With six terrorism-related deaths of senior military officers, as of April 2026, it already seems to be the worst year in the period. That is a sharp break from the pattern in earlier years, where losses were lower. It also suggests that attacks on military formations are not just continuing; they may be becoming more effective at reaching higher-ranking officers.
The chart also shows that this is not a nationwide pattern in equal measure. In early April 2026, Brigadier General Oseni Omoh Braimah was killed during an assault on a military base in Benisheikh, Borno. Days later, there were reports of another attack in Monguno, Borno, during which a colonel and other soldiers were killed.
Borno State dominates the geography, which fits the longer history of insurgent activity in the North East. Borno remains the centre of Nigeria’s longest-running insurgency, with recent reports suggesting that jihadist groups have regained momentum there.
