A bomb blast and gunfire shook an area around an Islamic boarding school in northern Nigeria, leaving two of the alleged attackers dead and at least three others wounded, officials said. It was not immediately clear who was behind the blast in the city of Zaria, but Islamist extremist group Boko Haram has been blamed for hundreds of deaths as part of its insurgency in northern and central Nigeria.
