The attack started at about 10 p.m. and was still ongoing one hour later. Witnesses said the attackers brought down police station and robbed banks and homes, reports Premium Times.
Some residents said the attack started around Daura Motel in the city centre before the attackers moved against banks and a police station.
Another witness said the attackers freed detainees at the police station in the town and then threw explosions at the station and prison.
It is unclear if the attackers are members of the extremist Boko Haram sect that has been terrorizing northern Nigeria since 2009.
The attack comes barely 48 hours after President Goodluck Jonathan declared a state of emergency in three northern states — Borno, Yobe and Adamawa.
Katsina, also home to late Umaru Musa Yar’Adua, under whose watch the Boko Haram sect transformed to a terror organization, has managed to remain insulated from the security crises in northern Nigeria.
