Keypoints:
- AES states reject Tinubu’s security assessment
- Burkina Faso calls his analysis overly simplistic
- Dispute exposes widening AES-ECOWAS divisions
NIGERIA’S President Bola Tinubu has drawn a sharp diplomatic rebuke from Burkina Faso, Mali and Niger after suggesting that deteriorating security in the neighbouring Sahel states was adding to Nigeria’s own struggle against terrorism and organised violence.
According to BBC News Pidgin, the three countries, which make up the Alliance of Sahel States (AES), summoned Nigeria’s chargé d’affaires in Ouagadougou and accused Tinubu of presenting an inaccurate picture of a regional security crisis in which soldiers and civilians across the Sahel continue to pay a heavy price.
The dispute matters beyond the immediate diplomatic exchange. Nigeria and the three AES states face many of the same cross-border militant networks, yet their political and security strategies are increasingly diverging as Abuja remains firmly anchored to ECOWAS while its northern neighbours build alternative institutions and partnerships.
Tinubu links insecurity to Sahel crisis
Tinubu made the comments while addressing traditional rulers in Nigeria on July 30, 2026, as he sought to explain the scale and complexity of the country’s security challenges.
He argued that not all militants operating inside Nigeria were Nigerian and directly linked Abuja’s security difficulties to instability across its northern borders.
‘Some of them [the terrorists] are not Nigerians. You see, the problem of insecurity in Mali, Burkina Faso and Niger is worsening our difficulties,’ Tinubu said, according to a translation of his remarks reported by BBC News Pidgin.
The comments put the three Sahel states at the centre of Tinubu’s explanation of Nigeria’s worsening security environment.
Nigeria is confronting several overlapping threats, including the Boko Haram insurgency and Islamic State-linked militants in the north-east, armed banditry and kidnapping in the north-west, as well as violent local conflicts in other parts of the country.
The AES governments, however, rejected what they saw as an implication that instability in their countries was being used to explain Nigeria’s security difficulties.
Burkina Faso calls analysis ‘simplistic’
Burkina Faso’s Foreign Minister Karamoko Jean Marie Traoré, speaking on behalf of Burkina Faso, Mali and Niger, said Tinubu’s assessment failed to recognise the sacrifices being made by Sahelian security forces and civilians.
Traoré sharply rejected the Nigerian president’s characterisation of the regional security situation.
‘It is a rapid, very simplistic and surprising analysis,’ Traoré said, according to a translation carried by BBC News Pidgin.
The three governments said they had expected Nigeria, as a neighbouring country confronting similar militant threats, to offer a more nuanced assessment of regional insecurity instead of appearing to shift responsibility towards countries north of its borders.
Their position is that terrorism across the Sahel and Lake Chad region is a shared security challenge requiring cooperation rather than assigning blame.
Traoré also stressed that the AES states had chosen engagement with Nigeria despite their objections to Tinubu’s remarks, describing regional security as a ‘joint and shared fight’.
Nigeria’s chargé d’affaires reportedly acknowledged the concerns and said the message would be relayed to authorities in Abuja.
The Nigerian diplomat also recognised what Burkina Faso described as the ‘considerable efforts’ being made by the AES states, including Niger’s contribution to preventing attacks that could have targeted Nigerian territory.
Political divide deepens security tensions
The disagreement comes as West Africa adjusts to a radically altered regional order.
Burkina Faso, Mali and Niger formally ceased to be ECOWAS members on January 29, 2025, after completing the one-year withdrawal process, although ECOWAS kept key free-movement and trade arrangements in place while discussions continued over the future relationship.
Since leaving the bloc, the three military-led governments have steadily expanded the AES from a security pact into a broader political and institutional project.
In December 2025, the alliance formally launched its multinational force, giving Burkina Faso, Mali and Niger a mechanism for coordinated military operations against armed groups operating across their territories.
The bloc has also moved into finance and communications. Its governments have established a regional investment bank intended to finance infrastructure, energy and agriculture, while AES Television has been launched as part of a wider effort to strengthen institutional and information sovereignty.
Russia adds geopolitical dimension
The AES states have simultaneously reduced security ties with several Western partners, particularly France, while strengthening their relationship with Russia.
That cooperation remains active. On July 8, 2026, AES foreign ministers met Russian Foreign Minister Sergei Lavrov in Niamey for a second round of consultations.
According to the Malian government’s account of the talks, the meeting strengthened cooperation between the AES and Russia in areas including political affairs, peace, security, development and counter-terrorism.
Nigeria, by contrast, continues to view ECOWAS as central to West African stability and works with regional and international partners on counter-terrorism efforts across the Lake Chad basin.
The result is a growing strategic divide. Abuja and the AES capitals are not simply pursuing different security policies; they are increasingly operating through different political institutions and cultivating different international partnerships.
Cooperation remains unavoidable
Yet geography leaves little room for lasting estrangement.
Nigeria and Niger share an extensive border and longstanding economic, cultural and security ties. Armed organisations operating across the Sahel and Lake Chad basin routinely exploit weakly governed territory and porous frontiers, making intelligence-sharing and cross-border cooperation essential.
The AES response also stopped short of signalling a break with Abuja. Its insistence that the countries should pursue a ‘joint and shared fight’ suggests that, despite the increasingly sharp political divide, practical security cooperation remains in the interests of both sides.
That may prove the most consequential aspect of the dispute.
Tinubu’s remarks have exposed the mistrust accompanying the widening political split between ECOWAS and the AES. But they have also underlined a strategic reality neither side can easily escape: Nigeria’s security and that of its Sahel neighbours remain deeply interconnected.
Whether Abuja and the AES governments can prevent their political differences from undermining security cooperation could become an increasingly important test for West Africa as militant organisations continue to operate across borders that divide governments far more effectively than they divide insurgents.
