At least seven other soldiers were injured in the operation early Thursday, said Gen Jacob Kodji. Kodji said the Nigerian Islamic extremist group launched a series of attacks in Cameroon earlier this week. “At least 27 Boko Haram fighters were killed in Thursday morning’s operation,” said Kodji, commander of Cameroon troops in the area. The soldiers remain on the battle front there, he added. Ashigashiya straddles the order of northern Cameroon and Nigeria. Regional forces from both countries have since December 2015 been launching raids on Boko Haram strongholds along their boarders. It will be recalled that six people were killed in Cameroon on Wednesday, February 10 , following a double suicide attack in the village of Nguetchewe, which lies close to the border.
