The killings, which took place across several villages and forested locations, including Takulawa, Turba, Bamamu, and parts of the Yamma forest, have sown fear and mistrust within Aleru's ranks.
Aleru, who appears on federal wanted lists, has been accused of masterminding kidnappings, killings, and cattle rustling across Zamfara, Katsina, and parts of Sokoto states.
Despite being engaged in peace talks with government representatives, the executions have raised fresh doubts about his sincerity in negotiations, given his violent track record.
Aleru's public profile has been controversial, with a chieftaincy title conferred upon him by the Emir of Yandoto Daji in Zamfara in 2022, despite security agencies maintaining bounties for his arrest.
His feud with another notorious leader, Dogo Gide, has sparked violent clashes, displacing communities and escalating insecurity across the North-West.
