The Nigerian city of Jos has been rocked by two bomb blasts killing at least 118 people and injuring many more.
The explosions happened in a crowded business district, incinerating several shops and causing damage to a wide area.
Police claim the attack bears the hallmarks of Boko Haram insurgents.
Although until now relatively free of militant violence, the city lies in the heart of Nigeria where the Christian south meets the Muslim north.
Boko Haram are currently the focus of internationally-aided efforts to locate 200 or more kidnapped schoolgirls.
One of them who managed to escape has accused her teachers of knowing about the attack and of saving themselves by preventing the girls from running away.
The girl who was too frightened to reveal her identity said somebody told them Boko Haram were coming to school. There was talk of the children running home but she claims the teachers said ‘no’.
Meanwhile in the capital Abuja there are daily protests against the government and its failure to act against the insurgents and recover the girls.
