A female suicide bomber detonated a bomb at a Federal College of Education Wednesday morning, killing at least three people, according to the BBC.
The bomber exploded outside of a packed lecture hall at a university in Kontagora. Lecturer Andrew Randa claims to have seen four bodies, although the casualty figures are still unclear.
Boko Haram, an Islamic terrorist group that has been active in northern Nigeria since 2009, has been confirmed as responsible for the bombing. The violent group have declared a caliphate, or Islamic state, across northeastern Nigeria.
This is the second bombing by the terrorist group to occur this week in Nigeria. The first bombing happened at a secondary school, Government Science School, on Monday (pictured) in Yobe State. The bomber, who wore a school uniform, bombed students as they waited in the assembly hall, killing 48 students and injuring 79.
