The operation on Friday was carried out by the Multinational Joint Task Force in a combined land and sea offensives on the enclaves of Boko Haram, said Timothy Antigha, a Nigerian military spokesman who also doubles as a spokesperson for the multinational force.

The operation was conducted in Doron Naira, an island in Lake Chad, and Nigerian border areas including Cross Kauwa and Baga in Nigeria's northeastern state of Borno, Antigha said.

The multinational force comprises troops from Nigeria, Chad, Cameroon, Niger, and Benin.

One soldier was killed in the confrontation with the Boko Haram fighters, and 10 other soldiers were wounded, the military official said.

Two gun trucks and three motorcycles were destroyed by the multinational troops, while two light machine guns and two AK-47 rifles were recovered from the terrorists, according to Antigha.

The operation, he said, would be further intensified through raids, ambushes and fighting patrols to clear terrorists from their last stronghold in the Lake Chad Basin.

Last December, Nigerian President Muhammadu Buhari and his colleagues of the Lake Chad Basin Commission renewed their commitment to ending the Boko Haram insurgency, declaring "a fight to finish."

Boko Haram has been trying since 2009 to establish an Islamist state in northeastern Nigeria, extending its attacks to countries in the Lake Chad Basin.

The group posed enormous security, humanitarian and governance challenges in the basin, according to the United Nations.
