Boko Haram: Bomber ‘attacks bus station’

A suicide bomber in north-eastern Nigeria has killed four people and injured other commuters at a bus station, witnesses have told the BBC.

He drove a car into the station on the outskirts of Potiskum in Yobe State, called over a girl selling water and then triggered the explosion, one said.

Potiskum has come under attack several times in the past from Islamist Boko Haram militants.

Last Sunday, two female suicide bombers targeted a market in the town.

That attack, in which four people died and more than 40 were injured, was blamed on Boko Haram – it has not commented.

Yobe is one of three states in North-eastern Nigeria which has been under a state of emergency for the last 20 months in a bid to end the Islamists’ six-year insurgency.

But in that time militant Islamist group had managed to seize control of a number of towns and villages in the area as part of its campaign to impose an Islamic state.
