Office of the National Security Adviser (ONSA) has warned Nigerians of possible isolated attacks by terrorist and criminal groups following sustained military operations against them in parts of the country.

In a security advisory dated August 27, 2026, ONSA urged Nigerians to remain vigilant and security-conscious, warning that groups suffering setbacks from ongoing security operations could resort to attacks aimed at creating fear and attracting public attention.

It said intelligence, security and law enforcement agencies, working with local and international partners, had intensified intelligence gathering and threat monitoring nationwide.

According to the advisory, sustained military and security operations across the North-East, North-West and North-Central had recorded notable successes against the Islamic State West Africa Province (ISWAP) and other criminal groups.

ONSA said the operations had resulted in the neutralisation of several terrorist and bandit commanders, including Abubakar Al-Mainok, alias Abu Bilal Al-Minuki, as well as the disruption of camps, hideouts and other criminal strongholds.
