Tens of suspected Boko Haram fighters were captured during a military operation conducted by Cameroonian forces in collaboration with Nigerian forces in the Lake Chad Basin, between Tuesday night and Wednesday morning, military sources have said.

The operation which happened about a month since the arrest of Boukar Kaou, one of Boko Haram commanders, with five other Boko Haram leaders as well as over 50 of the group's fighters in Madawaya forest along the border with Nigeria on the night of May 10, helped to dismantle another Boko Haram cell along the Cameroonian border.

The assault comes after the group carried out a deadly attack on Friday last week that killed 30 Nigerien soldiers as well as two Nigerian soldiers in Bosso, southern Niger, near the border with Nigeria.

Although said to be militarily weak, the terror group that is affiliated to Islamic State organization, has multiplied cells within its zones of influence, especially in northeast Nigeria and within Sambisa forest, a natural reserve that the West African nation shares with its Cameroonian and Chadian neighbours.

Still on Tuesday night, a Boko Haram attack against fishermen left "many victims" in Hile Hifa and Darack, two islands on Lake Chad within Cameroonian territory, the same sources told Xinhua on Wednesday.
