Police say members of a radical Islamist sect have shot and killed two people in northeast Nigeria.

Borno state police spokesman Samuel Tizhe said the shooting happened Monday in Maiduguri, in a neighborhood that once held the Boko Haram sect's main mosque. Tizhe said police continue to investigate the sect.

Meanwhile, witnesses say three people were injured Sunday night in a bomb attack in north Nigeria. That attack happened in Kano, a city where a January attack by Boko Haram killed at least 185 people.

Boko Haram is waging an increasingly bloody fight against Nigeria's weak central government in its effort to enact strict Shariah law across the multiethnic nation of more than 160 million people and free its imprisoned members.
