At least 81 people were killed and several are missing after an attack by suspected Boko Haram jihadists in Nigeria's northeastern Yobe State, local officials told AFP on Tuesday.

"Around 150 suspected Boko Haram terrorists armed with rifles and RPGs (rocket-propelled grenades) attacked Mafa ward on more than 50 motorcycles around 1600 hours on Sunday," said Abdulkarim Dungus, a Yobe state police spokesman.
