bomb blast again in this time located in kano

At least 20 others were wounded in the blast at the Kano School of Hygiene.
The city is known to have been targeted in the past by the radical Islamist group Boko Haram, which aims to create an Islamic state in northern Nigeria.
Three states to the east of Kano are under a government-imposed emergency after years of militant attacks.
Kano State police spokesman Magaji Majiya, who confirmed the attack, said eight people had been killed and many others with horrific injuries had been taken to hospital for treatment.
