Suicide blast kills 20 anti-jihadist fighters in Nigeria

A suicide attack in Nigeria's Borno state by a woman allegedly acting for Boko Haram insurgents has killed at least 20 anti-jihadist fighters, militia members told AFP on Saturday.

Police have confirmed 10 people were killed and said the overall toll could be higher.

Boko Haram and its rival, the Islamic State West Africa Province (ISWAP), have in recent months intensified attacks on villages in Borno and neighbouring states.

They have also overrun military bases, killing soldiers and carting away weapons.

Late on Friday, a woman allegedly detonated explosives strapped to her body at a haunt for vigilantes and local hunters assisting the Nigerian military in fighting "jihadists" in the town of Konduga, the militia told AFP.
