In Nigeria, at least seven people were killed when Boko Haram jihadists attacked a camp for people displaced by the conflict in northeast 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.<br/><br/>The camp in Ngala was set up in January last year after the return of thousands of Nigerian refugees from Cameroon, where they had fled the fighting. Militia members and locals today said the attack yesterday in Ngala, near the border with Cameroon, came as two people were killed in an explosion outside another camp in the Borno state capital, Maiduguri.
