Nigerian authorities have placed security forces on high alert following intelligence warnings of a planned large-scale assault by Islamist militants on key infrastructure in and around the capital, Abuja.
An internal memo dated 13 April, circulated within the Nigeria Customs Service and obtained by the Associated Press, indicates that militants intend to strike Nnamdi Azikiwe International Airport in Abuja, a prison facility in the capital, and a military detention centre in neighbouring Niger state. The stated aims are to free detained terrorists and cause major damage to aviation infrastructure critical to the country’s connectivity.
The document draws explicit parallels with an attack in Niger in late January, when militants assaulted an air force base adjacent to Diori Hamani International Airport in Niamey. That operation, claimed by Islamic State affiliates, involved coordinated strikes that damaged aircraft and highlighted vulnerabilities in regional air facilities.
Such patterns are not new to Nigeria. In 2022, gunmen linked to the Islamic State West Africa Province (ISWAP) stormed the Kuje medium-security prison on the outskirts of Abuja, enabling the escape of nearly 880 inmates, including dozens of suspected extremists. The episode exposed weaknesses in the protection of high-value detention sites and raised lasting concerns about the potential for repeat operations aimed at replenishing militant ranks.
According to the memo, the latest threat is attributed to sleeper cells connected to ISWAP — the breakaway faction of Boko Haram — and elements of Boko Haram itself. Both groups have waged a long-running insurgency in northern Nigeria, blending ideological extremism with tactics such as mass abductions for ransom and targeted strikes on security installations. A newer IS-linked outfit, Lakurawa, has also been active in north-western areas bordering Niger Republic.
A senior customs official, speaking on condition of anonymity because he was not authorised to discuss the matter publicly, told the Associated Press that military and paramilitary units were fully mobilised and prepared to prevent any attack. Neither the customs service nor the Nigerian military has responded to requests for comment.
The alert comes against the backdrop of a persistent and multifaceted security crisis in Africa’s most populous nation. More than a decade of violence in the north has left tens of thousands dead and millions displaced. While Nigerian forces have recorded some successes, including mass trials that resulted in hundreds of convictions of suspected militants in recent weeks, the groups continue to demonstrate resilience and the capacity to strike beyond their traditional strongholds.
The developments have drawn international attention. Last week, the United States authorised the voluntary departure of non-emergency government employees and their families from its embassy in Abuja, citing a spike in terrorist threats, kidnappings and violent crime, particularly in northern regions. The embassy itself remains operational but with reduced capacity for consular services. Nigerian officials, including Information Minister Mohammed Idris, have described the American move as a standard internal precaution that does not reflect the broader security reality on the ground.
For many observers, the latest warning underscores the enduring challenge Nigeria faces in containing jihadist networks that operate across porous borders with Niger and other Sahelian states. The targeting of airports and prisons carries symbolic as well as practical weight: successful strikes could disrupt commercial aviation, embolden recruits, and complicate efforts to hold captured fighters. Whether the heightened posture will deter the plot or merely delay it remains an open question in a country where intelligence leaks and operational successes have often proved uneven.
As Nigerian forces maintain vigilance, the episode serves as a reminder of the region’s fragile stability. Cross-border militant cooperation, evolving tactics, and the difficulty of securing sprawling infrastructure continue to test the limits of national and regional responses. For now, the capital and its critical sites stand on edge, with the outcome of the intelligence-driven mobilisation yet to unfold.
