Dozens killed as blast rocks Nigeria medical school

Dozens of people were killed Monday in a bomb blast in a medical school in Nigeria's northwestern state of Kano, officials said.

State police spokesperson Musa Majiya confirmed the incident, but said the official casualty figure could not been given immediately due to the ongoing rescue operation, Xinhua reported.

However, more than a dozen bodies were brought out following the incident at the Kano State School of Hygiene, a specialised medical institution located in the city's central business district.

Last week, 12 people were killed in an attack by suspected Boko Haram gunmen in Borno state.

Although no group claimed responsibility for the bomb attack, residents of the northwestern state blamed it on Boko Haram, an outlawed sect which had claimed responsibility for thousands of killings and kidnappings in Nigeria since 2009.
