Security has been tightened across the Federal Capital Territory following the circulation of an alleged classified security memo warning of possible coordinated terrorist attacks in the nation’s capital.

The document, reportedly attributed to the Department of State Services (DSS) and shared online, is said to have identified strategic targets including the Nnamdi Azikiwe International Airport, the Kuje Correctional Centre, and other sensitive government facilities in Abuja.

Although authorities have not confirmed the authenticity of the memo, security agencies have intensified deployments across key locations in the FCT.

The development reportedly follows an internal alert from the Nigeria Customs Service, which warned of potential plans by Islamic State West Africa Province (ISWAP), Boko Haram, Ansaru and JNIM to target critical infrastructure, including detention facilities in Abuja and neighbouring Niger State.

According to the report, the groups were allegedly planning coordinated attacks aimed at freeing detained insurgents.

In response, joint security operations involving the Nigeria Police Force, Nigeria Immigration Service, and the Nigerian Correctional Service have been reinforced, with increased patrols at airports, correctional centres, major highways and public spaces.

Checkpoints have also been strengthened across entry points into the capital, while stop-and-search operations have been intensified.

Residents have reported a visible increase in armed security personnel across major districts, with officials describing the measures as preventive steps aimed at deterring any potential threat and ensuring public safety.

Security agencies have continued surveillance operations as authorities monitor the situation.
