KANO: At least seven people were killed when Boko Haram jihadists attacked a camp for people displaced by the conflict in northeast Nigeria, militia members and locals said Saturday, reports AFP.

The attack on Friday evening in Ngala, near the border with Cameroon, came as two people were killed in an explosion outside another camp in Borno state capital, Maiduguri.

In Ngala, a civilian militia member, Umar Kachalla, said jihadists in two pick-up trucks fired a rocket-propelled grenade at the camp, which houses some 80,000 people.

"They fired an RPG into the camp from behind the fire fence, killing seven people and injuring several others," he told AFP, saying they let off a bout of sustained gunfire as they drove away into the night.

Ngala resident Abubakar Yusuf, who corroborated Kachalla's account, said: "The casualties were relatively minimal because most people had retired for the night."
