Fighting between Boko Haram and rival militants from the Islamic State West Africa Province (Iswap) group broke out in Dogon Chiku on the shores of Lake Chad on Sunday, in the latest bout of infighting for territorial control fuelled by ideological rifts.

"From the toll we got, around 200 Iswap terrorists were killed in the fight," Babakura Kolo, a member of an anti-jihadist militia assisting the Nigerian military, said.

A former Boko Haram jihadist, who has since renounced violence but follows jihadist activities in the region, also said "around 200 Iswap fighters were killed in the clashes", with several of their weapons seized.

Boko Haram lost four fighters in the battle, according to the former militant, who asked to be identified only by his first name, Saddiku.
