The Islamic State West Africa Province (ISWAP) has quietly announced the closure of its “hijrah” migration routes for foreign fighters, acknowledging that traditional entry corridors into Nigeria have become too dangerous due to sustained military operations by United States Africa Command (AFRICOM) and Nigerian forces.
According to intelligence report, sources who spoke to Zagazola Makama, a security analyst covering the Lake Chad region, disclosed that the terrorist group reportedly acknowledged that the routes, which have historically served as vital channels for the movement of fighters, weapons, supplies, and external support into insurgent-controlled territories, are now considered inaccessible.
Security sources described this development as evidence of increasing pressure on the group’s logistics infrastructure. The restriction on those corridors, they said, could complicate recruitment, logistics, and operational planning for the terrorist organisation.
The closure of migration routes coincides with a sustained campaign of intelligence-led strikes targeting ISWAP command structures and supply chains across Borno State and the wider Lake Chad region.
Military sources attributed the development to operations that have degraded several insurgent strongholds, decapitated top leadership, and disrupted mobility across the theatre.
One of the most significant outcomes of the campaign was the reported neutralisation of senior ISWAP commander Abubakar Mainok, also known as Abu Bilal Al-Mainuki, who allegedly exercised authority over operations extending across Nigeria, Niger, Chad, and Cameroon .
Mainok was killed alongside several close associates and senior aides. Among those reportedly neutralised were Abu Huraira, described as a key operational commander; Ba Yuram, who allegedly coordinated logistics, procurement, and weapons acquisition; and Mallam Haruna, identified as Mainok’s chief security aide .
A security source told Zagazola Makama that “the significance is not merely the loss of one commander but the reported disruption of an entire command ecosystem responsible for planning, logistics, security, and operational coordination” .
The operations, which began on May 15, 2026, have targeted key terrorist enclaves, supply routes, command centres, and logistics hubs across the North-East .
Battle damage assessments indicate that four major enclaves around Metele in Guzamala Local Government Area of Borno State were effectively neutralised. The affected locations included Garin Abu Bilal (Sahel), Garin Ba Bunu (west of Mangari), Satir-Kanama, and Kwatan Fulani .
At Garin Abu Bilal, also known as Sahel, assessment reports confirmed the neutralisation of Mainok alongside three foreign fighters described as Arab nationals. Approximately nine prominent operatives were eliminated, while about 20 others sustained varying degrees of injuries. The strike also destroyed five operational vehicles loaded with newly acquired weapons and concealed logistical supplies .
At Garin Ba Bunu, the strikes reportedly killed the coordinator of ISWAP’s taxation network and 26 other fighters. A learning centre described as an insurgent “madrasat” was also struck .
At Satir-Kanama, a major logistics warehouse containing motorcycles, engines, batteries, welding equipment, and mechanical tools was destroyed. Approximately six insurgents were killed, and 29 motorcycles were destroyed, crippling mobility and repair capabilities .
At Kwatan Fulani, described as a commercial logistics hub, airstrikes destroyed two fighting vehicles, with three fighters neutralised onboard. Over 30 shops, including food depots and fuel storage points, were also destroyed, severely disrupting economic and supply chains within the enclave .
Arege Operation
In a separate precision strike conducted around Arege in Kukawa Local Government Area, 21 ISWAP fighters were eliminated, including three mid-level commanders responsible for coordinating raids into Monguno and Damasak .
Retired Colonel Timothy Antigha, a member of the Minister of Defence Media Team, confirmed the operation, noting that “the strike marks another dividend from a defence relationship that has shifted from training-only to direct, intelligence-driven action against terrorist networks” .
Antigha explained that intelligence, surveillance, and reconnaissance assets observed terrorists assembling in Arege for possible attacks. The data was fused with US AFRICOM satellite imagery and signals intelligence. Once a cluster of 21 armed terrorists was confirmed in a concealed staging area, a joint strike was authorised .
“Arege sits on a key ISWAP supply route between Nigeria, Niger, and Chad. Eliminating fighters there disrupts three things: ISWAP logistics, as Arege is a hub for moving fuel, food, and ammunition to fighters in the Sambisa and Mandara corridors; recruitment, as the community has been a recruitment pool; and command and control,” Antigha said .
Impact on ISWAP Operations
The sustained military pressure has reportedly forced some insurgent elements to abandon traditional island sanctuaries and relocate to less secure locations where they remain vulnerable to surveillance and precision strikes .
Security sources noted that restrictions on migration and logistics corridors could complicate recruitment, logistics, and operational planning for the terrorist group. Leadership transitions within the organisation have also become a sensitive period, with reports that senior commander Ba’a Shuwa has shown reluctance to assume a broader leadership role following Mainok’s reported death .
“The growing vulnerability of senior terrorist leaders to intelligence-led operations may be contributing to hesitation among potential successors,” a source told Zagazola Makama .
According to the Defence Headquarters, the joint operations have eliminated 175 Boko Haram and ISWAP fighters since operations began on May 17, 2026. The DHQ described the killing of Al-Mainuki as “the single most consequential counterterrorism outcome in the North East Theatre since the inception of Operation HADIN KAI” .
A Strategic Shift
The operations represent a significant escalation in US-Nigeria military cooperation. President Donald Trump confirmed on May 16, 2026, that a joint operation killed Al-Mainuki, describing him as a top Islamic State leader in Nigeria .
Prior to this, US troops were largely restricted to advisory and training roles. Security analyst Bulama Bukarti noted that the new phase of operations demonstrates to militants “that the American-Nigerian operation has really picked up,” adding that Nigerian forces lack the basic capacity to fight violent extremist groups in densely forested areas like the Lake Chad region .
The Defence Headquarters has confirmed that the joint strikes will continue, with Major-General Samaila Uba, Director of Defence Information, stating that “the joint operations will continue to hunt down and destroy those who threaten the nation and regional stability” .
Cautious Outlook
Despite the reported gains, security analysts have cautioned that ISWAP remains a capable and dangerous organisation with the ability to adapt and reorganise. Several enclaves are believed to remain active across parts of the Lake Chad region, and security forces continue surveillance and offensive operations against surviving elements .
The Nextier policy think tank has warned that the killing of Al-Minuki may trigger fresh security threats, as rivalries between ISWAP and Boko Haram could intensify, potentially resulting in increased attacks on civilians .
