In the early hours of Saturday, US President Donald Trump announced the killing of Abu-Bilal al-Minuki, the ISIS commander described as the group’s second-in-command globally, during a joint military operation in Nigeria.
Trump said al-Minuki was eliminated in a “complex mission” conducted by American forces alongside Nigerian troops.
President Bola Tinubu later confirmed the operation, describing it as a “significant example of effective collaboration in the fight against terrorism”.
Security analysts say the death of al-Minuki — along with “several lieutenants” reportedly killed during the operation, could temporarily disrupt ISWAP’s operational coordination and weaken ISIS-linked activities across the Lake Chad region.
But who exactly was al-Minuki, and why is his death being viewed as a major moment in Nigeria’s counterterrorism campaign?
Here are 10 key things to know about the slain ISIS figure:
- Born in Borno with deep insurgency roots
Publicly available US sanctions records identify him as Abu Bakr ibn Muhammad ibn ‘Ali al-Mainuki, while Abu Bilal al-Minuki was listed among his known aliases. He was also known as Abor Mainok or Abubakar Mainok.
According to records from the US Office of Foreign Assets Control (OFAC), he was born in 1982 in Mainok, near Benisheikh in Borno State — an area long associated with insurgency activities involving Boko Haram and the Islamic State West Africa Province (ISWAP).
His background is significant because Borno State has remained the epicentre of Nigeria’s insurgency for more than a decade and has produced several influential jihadist commanders.
- ISIS expansion into Africa shaped his rise
ISIS was originally established in Iraq before expanding into Syria and becoming a transnational insurgency centred on the Iraq–Syria region.
Following the collapse of the ISIS caliphate in 2017, the US said the group splintered and shifted operations toward Africa and Central Asia, exploiting weak governance structures in those regions.
By late 2014, militant cells claiming affiliation with ISIS had already emerged across several conflict zones in West Africa.
Security experts believe al-Minuki’s rise reflected ISIS’s strategic push to strengthen its African networks.
- Under US radar and designated a global terrorist
The US State Department officially designated al-Minuki as a Specially Designated Global Terrorist (SDGT) on June 8, 2023.
The designation subjected him to American counterterrorism sanctions, blocked assets linked to him within US jurisdiction, and prohibited Americans from engaging in transactions connected to him.
The Federal Register notice published on June 16, 2023, identified him as a key figure in ISIS-linked operations in West Africa.
- Arrived in the Lake Chad region with foreign fighters
Security and intelligence sources familiar with extremist activities in the Lake Chad Basin say al-Minuki entered the region alongside nearly 60 foreign fighters deployed to strengthen ISWAP’s battlefield structure and operational capabilities.
The fighters who accompanied him were believed to possess combat experience from the Middle East and other jihadist theatres. Their arrival reportedly introduced a more advanced phase of insurgent warfare into Nigeria’s conflict environment.
- Introduced sophisticated ISIS-style tactics
The arrival of al-Minuki and his fighters coincided with major tactical changes in ISWAP operations, including:
Increased night assaults on military formations
Coordinated raids using mobile attack teams
Deployment of armed drones for surveillance and attacks
More sophisticated use of improvised explosive devices (IEDs)
Renewed suicide bombing campaigns
Improved battlefield communication and logistics coordination
These tactics closely resembled methods used by ISIS fighters in Iraq and Syria.
Al-Minuki was also believed to have coordinated international funding channels that enabled the use of armed drones in jihadist attacks.
- Rivalry with Shekau deepened Boko Haram divisions
According to the International Crisis Group, al-Minuki had a difficult relationship with former Boko Haram leader Abubakar Shekau.
Despite benefiting from ISIS support, Shekau reportedly resisted attempts by ISIS leadership to exert authority over him. When ISIS requested 1,000 ISWAP fighters to assist in defending Sirte, Libya, Shekau reportedly declined.
After Shekau rejected the request, al-Minuki — then serving as ISWAP’s Lake Chad area commander — allegedly sent fighters independently.
The decision reportedly widened divisions between commanders loyal to ISIS central leadership and Shekau’s faction.
By mid-2016, ISWAP split into rival factions as opposition to Shekau intensified.
- Emerged stronger after Mamman Nur’s death
In 2018, ISWAP leader Mamman Nur was executed by members of the terrorist group amid internal disagreements, including tensions surrounding the handling of the Dapchi schoolgirls kidnapping.
On February 19, 2018, ISWAP fighters abducted 110 girls from the Government Girls’ Technical School in Dapchi, Yobe State.
Following Nur’s death, al-Minuki emerged as one of ISWAP’s dominant figures alongside commander Mustapha Kirmima.
The Nigerian military later linked him to the Dapchi abduction.
- Became a major ISIS regional coordinator
In 2020, al-Minuki was identified as ISWAP’s second deputy emir in a letter addressing the group’s leadership crisis.
It remains uncertain when he assumed leadership within ISIS’s al-Furqan office, regarded as one of the group’s strongest regional coordination networks.
The al-Furqan office reportedly oversees ISIS-linked operations across Nigeria, neighbouring countries, and the Islamic State in the Greater Sahara (ISGS) affiliate operating in the western Sahel.
The office is believed to provide operational guidance, funding, strategic communications, and coordination for ISIS affiliates throughout West Africa.
- Considered ISIS’s global number two
Trump described al-Minuki as one of the world’s most dangerous ISIS leaders and said his death would significantly weaken the terror group’s international operations.
The US president stated that the militant would no longer “terrorize the people of Africa” or support plots against American interests.
ISWAP remains one of the deadliest extremist groups operating in the Lake Chad region, carrying out attacks across Nigeria, Niger, Chad, and Cameroon.
Security experts believe al-Minuki’s influence highlighted how deeply global jihadist networks remain connected to local insurgencies in West Africa.
- Why his killing matters
Eliminating a commander of al-Minuki’s stature could disrupt ISIS financing, recruitment, logistics, and operational planning across West Africa.
However, analysts caution that extremist organisations often replace senior commanders quickly, meaning the long-term impact will depend on sustained intelligence efforts and military pressure.
For Nigeria, the operation represents both a major security breakthrough and a reminder that the country remains central to the global fight against terrorism.
Until Nigerian authorities release fuller operational details, many aspects of the mission — including how al-Minuki was tracked and eliminated — remain subject to official confirmation.
