Renewed violence erupted Tuesday evening in Damaturu, the Yobe state capital as suspected members of Boko Haram clashed with the combined team of army and the police.
Witnesses claim gunmen launched attacks against the police station in Goron Dutse with explosives and guns.
According to a Joint Task Force (JTF) source, who does not want to be named, the renewed hostility in Damaturu started around 6pm, Tuesday evening.
The JTF official told Channels Television that explosions and gun shots were targeted at the Federal Polytechnic Damaturu and the personal residence of the state governor.
The source also confirmed that three attackers were killed in the process as three arms were recovered. According to the source, a structure at the polytechnic was razed but the attack was repealed by operatives of the Joint Task Force that rushed to the scene.
The police are yet to confirm the attack.
A 24 hour curfew was placed on the city after the violence that erupted last Sunday but was later relaxed after a reasonable sense of normalcy returned to the north eastern city.
