At least 47 teenage boys have been killed in a suicide bombing at an all boys school in northeastern Nigeria in the town of Potiskum, many of those killed were students. Potiskum is located in Yobe, one of three states placed under a state of emergency by the government last year due to the Boko Haram insurgency.
The attack happened as students gathered for a morning assembly at a government-run secondary school which focused on science.
Medical workers said at least 79 people were injured in the blast, many of them seriously. Witnesses said the bomber was dressed like a student.
No one has claimed responsibility for the attack, but suspicion has fallen on Boko Haram.
Boko Haram, whose name roughly means “Western education is forbidden,” has attacked schools before, most notably when it kidnapped more than 200 girls from a secondary school in the town of Chibok in April.
The group was blamed for an attack in Potiskum one week ago, when a suicide bomber attacked a religious procession, killing more than two dozen people.
UN Secretary-General Ban Ki-moon has called on Nigerian authorities to bring the perpetrators of the school attack to justice.
The UN chief “is outraged by the frequency and brutality of attacks against educational institutions in the north of the country”, his spokesman said
