An explosion at a school in Kano, Nigeria, Monday has left eight people dead, reports the Associated Press. According to the BBC, Kano State police spokesman Magaji Majiya said "at least" eight were killed and at least 20 others wounded in the blast.

A teacher at the Kano School of Hygiene told the Agence France-Presse news agency that the explosion is believed to have originated at a parking lot next to the post-secondary training school.

While there is no official confirmation of responsibility for the attack, the BBC is reporting that one unidentified individual has been arrested. Nigeria’s second city is known to have been targeted by the radical Islamist group Boko Haram in recent months.

The last explosion in Nigeria to result in fatalities occurred June 17 at a World Cup game viewing station in the town Damaturu in Yobe state. The Los Angeles Times reported Wednesday that at least 14 individuals, including children, were killed by the blast. Approximately 26 people were wounded.
