The Nigerian Army on Saturday confirmed the death of one soldier, a State Security Service official and nine gunmen suspected to be members of the Boko Haram sect in a gun duel in Okene, Kogi.
The incident occurred between Friday night and Saturday morning.
The Brigade Commander in-charge of Chari Maigugeri Barracks in Lokoja, Maj.-Gen. Alphonsus Chukwu, told newsmen in Okene, that three SSS officials were also wounded in the attack.
He said the SSS officials were receiving treatment at the Federal Medical Centre, Lokoja.
Chukwu said a combined team of soldiers, SSS and police tracked the suspects to their hideout in Okene on Thursday.
He said the team decided to invade the hideout, an uncompleted building, late Friday night.
Chukwu added that the gunmen had informed some banks in writing of an impending attack on their branches, adding that as a result of this, security agents started trailing them.
However, some members of the sect escaped onto mountain tops in Okene from where they fired shots at the security officers.
Chukwu said items recovered from the hideout included hand grenade, two pistols, Improvised Explosive Devices and five magazines of AK 47 painted in police colour and motorcycles.
He said security agents would remain on the spot until all the suspects were routed.
The News Agency of Nigeria reports that an Air Force helicopter was seen hovering around the town around 4:30 pm on Saturday.
Chukwu said the helicopter would locate the suspects that fled onto mountain tops.
