The offensive on Saturday followed intelligence that the extremist group planned to attack
the restive city of Damaturu again, said the deputy police spokesman of Yobe state.
“Security operatives were able to discover a plan by Boko Haram hoodlums to launch attacks in the city,” said Gbadegesin Toyin.
The Joint Task Force (JTF) military unit “located their positions… they cordoned off these positions and engaged the gunmen in a shootout,” he added.
He said soldiers fired mortar rounds at the Islamist militants, who responded with gunfire and also threw improvised explosive devices.
The violence was most heavily concentrated in the Nyanya and Obasanjo Estates areas of the city, he said.
“Three suspected Boko Haram militants were killed and a female sect member was arrested. The hideout was destroyed in the raid,” Toyin added.
Nigerian authorities on June 19 slapped a round-the-clock curfew on Damaturu, after suspected Boko Haram Islamists launched coordinated gun attacks on targets around the city.
The curfew was partially relaxed two days later after soldiers and police reclaimed control of the streets in an offensive that left at least 40 people dead, including 34 alleged Boko Haram members.
The ban on movements was further eased on Monday, but Damaturu residents are still forced to remain in their homes between 6pm and 7am.
Damaturu has repeatedly been hit by the radical Islamist group, responsible for more than 1,000 deaths since the middle of 2009 in Africa’s most populous nation and largest oil producer. Yobe state borders the extreme northeastern state of Borno, where the capital Maiduguri is considered Boko Haram’s base.
The Islamist group’s insurgency, concentrated in Nigeria’s mainly Muslim north, has frequently targeted the security forces, though the Islamists have attacked churches and other symbols of authority.
The government’s response to Boko Haram in past months has included heavy-handed military raids, which had angered residents of hard-hit areas and failed to stop the extremists.
Last week, President Goodluck Jonathan fired his national security adviser and defence minister, amid intensifying criticism of his administration’s response to the Boko Haram threat.
The Islamist group initially said it was fighting for the creation of an Islamic state, but its demands have since shifted repeatedly. It is believed to have a number of factions, including a main Islamist wing.
Many say deep poverty and frustration in the north have been main factors in creating the insurgency.
Police in Nigeria’s central Plateau State said yesterday they had foiled a bid to blow up a bridge in a restive area that has been hit by ethnic violence and Islamist attacks.
State police spokesman Emmanuel Abuh said that explosives hidden under a busy bridge were removed on Saturday following a tip-off. The bridge is near the state capital Jos.
