A new report by the Conflict Armament Research group said some of the weapons from Turkey were linked to a major organized trafficking network.
It explained that the weapons were used in the killing of more than 3,600 people and displaced 300,000 since 2014,
It noted that fighting between farmers and herders over land has gone on for decades in the middle belt and north.
The report further said armed groups involved in the bloodshed in Kaduna, Katsina and Zamfara states possessed significant numbers of factory-produced small arms manufactured in Europe, East Asia, the Middle East and North America,” according to the three-year study.
It said, “Weapons that Conflict Armament Research documented during field operations in three northern Nigerian states have commonalities with small arms previously in service with national defence forces in Côte d’Ivoire and with weapons that CAR has documented in Libya.”
It noted that the set of weapons from northern Nigeria also includes Iraqi assault rifles manufactured in 1987.
It further said the terrorist groups have used weapons from the same batch with batch markings rendered illegible.
The report read, “Predictably, given widespread weapon diversion from many governments in the region, CAR has traced four weapons in the data set to the stockpiles of Nigerian defence and security forces.
“Nigerian-manufactured small-caliber ammunition—including cartridges manufactured as recently as 2014—is the second-most prevalent type of ammunition in this data set.”
The study further noted that in 2016, the Presidential Committee on Small Arms and Light Weapons and the Mines Advisory Group, collected weapons in Katsina, nearly 6,000 in Zamfara, and almost 700 in Benue.
