Boko Haram fighters and its splinter Islamic State West Africa Province (ISWAP) group have for more than a decade battled the Nigerian army in a conflict that has sucked in neighbouring states.
Multinational Joint Task Force spokesman Colonel Muhammad Dole said troops had ventured deep into enclaves controlled by insurgents in the Lake Chad area and recovered several weapons, food and illicit drugs.
“Within the period of this operation, well over a hundred terrorists have been neutralised, including over 10 top commanders … following intelligence-driven lethal air strikes in the Lake Chad islands by the combined air task-forces,” Dole said.
Dole did not give the period covered by the operation or number of troops killed but said 18 soldiers were injured by improvised explosive devices planted by retreating insurgents.
The Islamist insurgency is concentrated in the northeast of Nigeria and has left thousands dead while driving millions from their homes into camps for internally displaced persons.
Nigeria received a boost after the United States last week approved a nearly $1 billion weapons sale. U.S. lawmakers had put a hold on the deal over concerns about possible human rights abuses by the Nigerian government.
Boko Haram has been on the back foot since the death of its leader, Abubakar Shekau, last year in May during a battle with rival ISWAP. Nigeria says thousands of Boko Haram fighters and their families have surrendered since last year.
