Fifteen people killed in attack on Nigerian college

Officials said at least fifteen people were killed in an attack on a teachers training college in the northern Nigerian city of Kano by a group of armed gunmen on Wednesday. Over 30 others were wounded.

News agencies have reported while there has been no claim of responsibility, suspicion will likely fall on the Islamist extremist group Boko Haram. The group has previously targeted Western-style schools within the country, including past attacks on secondary schools.

According to official reports, police first approached the group in the area of the school, concerned about their unusual activity, and the attackers engaged police in a firefight. The attackers gained entry to the school and started throwing bombs.

Nigerian President Goodluck Jonathan described the incident as a "dastardly attack". He has already declared a state of emergency in three northern states, and is being criticized along with the country's armed forces for failure to prevent extremist attacks.

A police spokesman said police killed two attackers at the scene.
