In pictures: Aftermath of bombing in Nigerian town of Potiskum

On Sunday, two female suicide attackers killed four people and injured more than 40 in the town of Potiskum in north-east Nigeria.

The attack has been blamed on Boko Haram, the militant Islamist group that has seized control of a number of towns and villages in the area as part of a campaign to impose an Islamic state.
