Boko Haram ‘ambushes’, kills 10:

Boko Haram extremists ambushed an oil exploration convoy in northern Nigeria, killing at least 10 people and abducting several others who were later rescued, officials said Wednesday. They said insurgents also had been killed, but gave no numbers.

The ambush came several weeks after the Nigeria National Petroleum Corporation’s management announced it was resuming oil exploration around Lake Chad following assurances by Nigeria’s military that security had improved in the area, which was once under Boko Haram’s control. (AP)
