Jihadist groups are increasingly carrying out drone strikes in West Africa, raising alarm that they are building the capacity to wage a "war from the skies".

A leading violence monitoring organisation, Acled, has recorded at least 69 drone strikes by an al-Qaeda affiliate in Burkina Faso and Mali since 2023, while two Islamic State (IS) affiliates have carried out around 20 - mostly in Nigeria, which has been battling numerous insurgent groups for almost 25 years.

The latest drone attack took place in Nigeria's north-eastern Borno state on 29 January, when jihadists carried out a two-pronged assault - with multiple armed drones and ground fighters - on a military base.

The military said nine of its soldiers were killed in the attack by the Islamic State of West Africa Province (Iswap) - identified by Acled as the "most prolific" IS African affiliate in "drone warfare".

The jihadists tended to carry out strikes with "commercially available, relatively inexpensive quadcopter [unmanned] drones" that were "rigged with explosives", while also using them for reconnaissance and surveillance missions in preparation for ground attacks, Acled senior Africa analyst Ladd Serwat told the BBC.

Despite the fact that Nigeria's government tightly controls the import of commercial and hobby drones and prohibits their use without official permission, the jihadists were able to obtain them through their smuggling networks across the region's porous borders, said a Nigeria-based senior researcher at the Good Governance Africa think-tank, Malik Samuel.

"The growing use of armed and surveillance drones by violent extremist groups in the Sahel and Lake Chad region is deeply concerning, and it marks a significant shift," security analyst Audu Bulama Bukarti told the BBC.

"Drones lower the cost of conducting attacks, allow militants to gather intelligence with minimal risk and enable strikes on military targets that were previously harder to reach," he added.

According to Serwat, Iswap has carried out 10 drone strikes since 2024 in north-eastern Nigeria as well as in northern Cameroon, southern Niger, and southern Chad - all countries affected by the insurgency in Nigeria.

A similar number of drone attacks were carried out by another IS affiliate, the Islamic State of Sahel Province (ISSP), in West Africa, Acled data shows.

In its latest attack, ISSP carried out an assault on the international airport in Niger's capital, Niamey, and nearby military bases, also on 29 January, with the defence ministry saying that four military personnel were injured and 20 of the assailants were killed.

Serwat said that while some reports claim ISSP used mortars and RPGs, others suggest that the militants carried out a drone strike.

"If a drone was used, this represents the first time ISSP used an explosive-laden drone in Niger," he added.

The jihadist group that has used drones the most is the al-Qaeda-affiliated Jama'at Nusrat al-Islam wal-Muslimin (JNIM). Acled says it has carried 69 strikes in neighbours Mali and Burkina Faso, and one across the border in Togo.

"JNIM's drone programme has developed rapidly and spread across interconnected networks in Mali and Burkina," Acled's senior West Africa analyst Héni Nsaibia said.

Military Africa, an online defence industry source, reported that last February, JNIM had also used what are known as first-person view (FPV) drones - when the pilot has a live feed from the drone - to drop improvised explosive devices, made from plastic bottles, onto military positions in Burkina Faso's Djibo town.

"This marked a significant escalation, as FPV drones - small, agile, and often used in Ukraine - allow precise targeting," Military Africa reported.

Samuel said the jihadist groups were influenced and trained by foreign fighters to constantly adopt new methods - from making roadside bombs and suicide belts, they had now learned to turn "off-the-shelf" drones into weapons.

Drone attacks could reduce casualties among jihadists, while achieving greater "effectiveness" in hitting targets, Samuel said.

Acled analyst Nsaibia told the BBC that while the majority of JNIM's drone attacks in Mali and Burkina Faso had targeted the military and allied militias, some had also hit civilians, including markets in communities perceived as being aligned with government forces.

As for Iswap, it was known to have carried out only one drone attack that hit civilians - in June 2025, when two pastoralists were killed and one injured in northern Cameroon, Nsaibia said.

In a report last year, a researcher at the South Africa-based Institute for Security Studies, Taiwo Adebayo, wrote that to combat the threat, West African armies needed to carry out "preemptive strikes" to destroy drone assembly and launch sites, and acquire more counter-drone technology, including jamming devices and air defence systems.

Otherwise, he warned, the jihadists could enhance their drone warfare capabilities and carry out "high-impact assaults" that could worsen instability in West Africa.
