Cameroon says it has liberated a Boko Haram stronghold in northeastern Nigeria, killing more than 150 militants and destroying weapons and bomb factories.

The Cameroonian military launched raids on Goshi in northeastern Nigeria, 15 km (9.3 miles) from the border with Cameroon, between February 11-14, according to the country’s Communications Minister Issa Tchiroma Bakary, Voice of America reports. During the raids, 162 Boko Haram fighters were killed, four mine factories destroyed, a training center for militants set on fire and weapons seized, Bakary said, adding that Nigerian hostages were also freed.

Boko Haram has been suspected of carrying out attacks in Cameroon and other countries neighboring Nigeria in the Lake Chad region. Two female suicide bombers killed at least six people at a funeral on February 10 in the village of Nguetchewe, close to the Nigerian border. A quadruple suicide attack at a market in Cameroon’s Far North region in January killed around 25 people.
