Nigeria's army has driven Boko Haram from its last camp in the Islamist militant group's northeastern Sambisa forest stronghold, the country's president has said.
It follows a large-scale offensive by the military in recent weeks to reclaim the vast former colonial game reserve that has been the group's base.
President Muhammadu Buhari said: "I was told by the Chief of Army Staff that the camp fell at about 1:35 p.m. on Friday, Dec. 22, and that the terrorists are on the run and no longer have a place to hide."
Boko Haram kidnapped almost 300 school girls from Chibok in 2014.
In October, Nigerian officials confirmed the release of 21 girls who were kidnapped two years ago.
