Nigerian troops on Saturday killed 19 Boko Haram insurgents during a gunfire exchange in an operation in Borno state.
In a statement, the army said it acted on an intelligence report on the presence of Boko Haram fighters in the Chuku-ngu-du camp. The leader of the terrorist group in the area, Ameer Abubakar Gana, was also killed.
The troops also destroyed an explosives factory, detonated four improvised explosive devices and recovered two anti-aircraft guns and other weapons.
On Friday, 32 soldiers were killed in a clash with Boko Haram on Niger’s border with Nigeria. Thirty of them were from Niger and two from Nigeria.
At least 20,000 Nigerians have been killed and more than 2.1 million displaced by Boko Haram’s seven-year insurgency.
In Niger, the UNHCR estimates that just over 50,000 people are displaced within the country.
