Gunmen in northern Nigeria have attacked a police station in Jigawa State in spite of the state of emergency declared by President Goodluck Jonathan on New Year's Eve.They killed a teenage girl and wounded a police officer.

The incident was reported by AFP.

"The gunmen shot indiscriminately into the police station and engaged our men in a shootout, killing a teenage girl trying to flee and wounding a policeman," Jigawa state police commissioner Hashimu Argungu said of the attack late Tuesday.

"They threw an explosive into the police station but it did not detonate, which saved the police station from being destroyed, although its walls were riddled with bullets from the attack."

Argungu said an investigation was ongoing and he could not yet say who was behind the attack. Scores of such attacks in Nigeria's north have been blamed on Islamist group Boko Haram.
