LAGOS, Jan. 23 (Xinhua) -- Authorities in Nigeria's northwestern state of Kaduna said Saturday that a group of unidentified gunmen attacked two local government-controlled areas in the state and killed six people, while eight others sustained varying degrees of injuries.
The gunmen, suspected to be bandits, raided some communities in Chikun and Giwa areas in large numbers, said Samuel Aruwan, the commissioner for internal security and home affairs in the state.
Aruwan said security operatives have launched an investigation into the incident.
He urged security agencies to ramp up responses to curb such attacks.
Banditry, kidnapping and other criminal activities have been rampant in Nigeria's northwest region for years.
