EXCLUSIVE: Boko Haram–ISWAP rivalry escalates into full-scale territorial war across island corridors

The Lake Chad Basin is witnessing a dangerous escalation in insurgent-on-insurgent warfare, as a fresh wave of violent clashes between rival jihadist factions Boko Haram’s Jama’atu Ahlis Sunna Lidda’awati wal-Jihad (JAS) and the Islamic State West Africa Province (ISWAP) intensifies across strategic island strongholds and riverine settlement routes in Abadam and Kukawa Local Government Areas of Borno State.
Between 5 and 8 November 2025, Boko Haram’s Jama’atu Ahlis Sunna Lidda’awati wal-Jihad (JAS) launched a fierce coordinated assault on its rival faction, Islamic State West Africa Province (ISWAP), across a stretch of islands identified as Sahel 1, Dogon Chuku, Mangari, and linked riverine basins spanning Tumbun Gini – Tumbun Dalo – Tumbun Shanu – Mangari – Dumba in Abadam and Kukawa local government areas of Borno State.
The fighting was intense. The objective was clear. JAS wants to erase ISWAP. Sources revealed that JAS fighters, led by commanders Hassan Buduma and Mohd Hassan, mobilised multiple watercraft loaded with fighters and heavy weapons, moving in waves from Tumbun Gini through the upper river basin to Tumbun Dalo, Tumbun Shanu, Mangari, Dumba and surrounding islands, a chain of sandy enclaves where humanitarian presence is almost non-existent.
In a scene described as “an amphibious assault in insurgent style,” JAS fighters attacked ISWAP from the water, surprising them at dawn. “This is not a misunderstanding, this is a takeover,”said one intelligence source familiar with the region.
However, after days of sustained fighting,
ISWAP fighters were forced to abandon their river camps scrambling for their lives.
The number of casualties remains unknown, but ISR reportedly picked up heat signatures of several bodies floating and others buried in shallow sand pits.
Multiple sources also confirmed that JAS deployed several motorized watercraft in a multi-axis assault, overrunning ISWAP clusters and pushing surviving fighters off the island perimeter into mainland hideouts around Ali Jillimari, Metele, Kangarwa, and Gudumbali in North of Borno.
While both groups share an extremist ideology, the battle has nothing to do with religion. It is about power. Control of the Lake Chad islands means control of millions of naira collected through extortion of fishermen and traders, they will also take control of the Arms and fuel smuggling corridors through Niger, Chad and Cameroon. They will also have mobility advantage where the water channels provide a perfect cover from air surveillance.
ISWAP had dominated these islands since 2021, after the death of Boko Haram leader Abubakar Shekau. But water levels have receded this season, opening new land routes and exposing old fishing settlements.
At the core of this escalation is not ideology — but dominance. JAS, according to intelligence intercepts, has vowed to “totally eliminate ISWAP presence in the Lake Chad islands”, and seize ISWAP’s lucrative supply corridors interfacing Niger, Chad and Cameroon.
JAS reportedly plans to push further south toward ISWAP headquarters within Marte and Ngala LGAs, a strategic move that, if successful, would reverse ISWAP’s dominance for the first time since 2021. Once ISWAP regroups on the mainland, it will retaliate violently to reclaim the islands. The group has never allowed a territorial defeat to stand.
Zagazola report that the clashes represent a transition from sporadic skirmishes to a full territorial campaign. More ambushes, roadside bombs and abductions along access routes linking Metele, Kangarwa and the Maiduguri–Damasak MSR, should be anticipated.
The emerging trend suggests that both factions will now lunched retaliatory raids on each other’s strongholds, attack supply lines, including river transport. Communities in Kukawa and Abadam especially fishermen, transport boat operators, and seasonal farmers will bear the immediate consequences.
The Lake Chad Basin has always held strategic value a place where borders blur and armies struggle to manoeuvre. But this new insurgent rivalry marks a turning point. For the first time in years, Boko Haram and ISWAP are not just fighting the state. They are fighting over who gets to rule the shadows.
And somewhere in the middle caught between gunboats, ideology and hunger are the civilians of the Lake Chad islands, whose lives continue to be shaped by a war they did not choose and cannot escape.

Zamfara: Troops neutralise terrorist, recover arms in Shinkafi LGA
By Zagazola Makama
Troops of the 1 Brigade of the Nigerian Army operating under Operation FANSAN YANMA have neutralised a suspected terrorist and recovered arms during an offensive operation in Shinkafi LGA.
Security sources told Zagazola Makama that the operation was carried out on March 13 by troops of CT 5, who launched a deliberate clearance mission targeting terrorist camps located at Tubali and Zangon Danmaka.
The sources said the operation followed credible intelligence on the presence of armed bandits and other criminal elements using the locations as operational hideouts.
During the operation at Tubali, troops made contact with the suspected terrorists and engaged them in a brief gun battle, forcing the criminals to flee into nearby forested areas.
“During the engagement, one terrorist was neutralised, while others escaped with possible gunshot wounds,” the source said.
Following the encounter, troops conducted exploitation of the area and recovered one AK-47 rifle, a magazine containing two rounds of 7.62mm special ammunition, and a motorcycle believed to belong to the fleeing terrorists.
The recovered items were secured by the troops while further search operations were carried out around the camp to ensure that no other threats remained in the vicinity.
The sources added that when troops advanced to Zangon Danmaka, no contact was made with terrorists as the suspects were believed to have fled the area ahead of the troop arrival.
However, troops maintained dominance in the general area while conducting further patrols and surveillance operations aimed at preventing the terrorists from regrouping.

Troops arrest suspected ISWAP spy in Kanama, Yobe
By Zagazola Makama
Troops of 159 Battalion in collaboration with members of the Civilian Joint Task Force have arrested a suspected spy linked to terrorists operating in the North-East in Kanamma Yobe state.
Security sources told Zagazola Makama that the suspect, identified as Malam Fantami, a native of Dikwa was apprehended during a security operation by troops deployed in the area.
The sources said the suspect was intercepted following credible intelligence indicating that he might be working as an informant for terrorists affiliated with the ISWAP.
According to the sources, items recovered from the suspect at the time of his arrest included a mobile phone, a smart watch, prayer beads, a motorcycle key, and a cash sum of ₦7,000.
Preliminary examination of the suspect’s mobile phone by security personnel reportedly revealed several suspicious materials, including photographs of motorcycles, large sums of cash, AK-47 rifles and other items believed to be linked to terrorist activities.
“The discovery of these materials has raised serious suspicion about the suspect’s role as a possible logistics informant or intelligence asset for insurgent elements operating in the region,” the source said.
The suspect is currently in military custody, where he is undergoing further interrogation to determine the extent of his involvement with terrorist networks and to identify possible collaborators.
The military high command said the arrest forms part of ongoing counter-terrorism efforts by troops in the North-East aimed at dismantling the intelligence and logistics networks that support insurgent operations.
Kanama, located in Yunusari Local Government Area of Yobe State near the border with Niger Republic, has remained an important corridor frequently exploited by insurgent groups for movement and supply activities.

Troops of Operation HADIN KAI successfully repelled an attack by terrorists suspected to be members of ISWAP in Bita area of Borno state following a fierce overnight encounter.
Security sources said the attack began at about 1:09 a.m. on Saturday, when the insurgents launched a coordinated assault on troops of the 26 Task Force Brigade deployed in the Bita axis.
According to the sources, the terrorists attempted to overwhelm the troops’ position but were met with stiff resistance from the soldiers who engaged them in a sustained gun battle.
“In a decisive and coordinated operation, gallant troops of Operation Hadin Kai launched a simultaneous land and air assault on terrorist positions in Bita in the early hours of today,” the source said.
The coordinated response involved ground troops engaging the insurgents while aerial support conducted precision strikes and surveillance over the battlefield, forcing the attackers to retreat.
The intense engagement compelled the terrorists to withdraw towards their enclaves after suffering heavy pressure from the combined land and air assault.
Following the withdrawal of the insurgents, troops immediately commenced exploitation operations to pursue fleeing elements of the terrorist group and prevent them from regrouping.
