We are unable to get confirm exact casualty figure at this time but the Bauchi State Commissioner of Police, Mohammed Ladan, told Aljazeera TV that at least eight people were killed.

A resident of the quarters, who preferred anonymity, said he witnessed the incident, adding that the gunmen fired close-range shots at Mr. Magaji.
The deceased was a civil servant in Gombe Local Government before he left the service for business.
