Nigeria's military says troops freed 338 captives, mainly children and women, in raids on Boko Haram camps in northeast Nigeria.
Nigeria's Defense Headquarters says 30 militants of the Islamic extremist group were killed in Tuesday's attacks on the fringes of the Sambisa Forest.
A military statement on social media says troops separately ambushed and killed four suspects who were on a suicide bombing mission in northeastern Adamawa state.
The military posted photographs of several guns and ammunition recovered, along with images of bodies of alleged insurgents.
Nigerian troops have rescued hundreds of Boko Haram captives this year but none of the 219 girls kidnapped from a school in Chibok. Their mass abduction in April 2014 sparked international outrage against the militants.
