Earlier this week, one Amina Ali Nkek, another girl who was kidnapped, was found by a local vigilante group near the Nigerian-Cameroonian border.
In April 2014, the Boko Haram militant group attacked a boarding school in Chibok, kidnapping 276 girls. Some of them managed to escape within hours after the kidnapping, but a total of 219 remained missing until this week’s rescue.
The Boko Haram extremist group began large-scale attacks in northeast Nigeria in 2009. Last year, the group expanded attacks into neighboring Niger, Cameroon and Chad. The extremist group pledged allegiance to the Islamic State, outlawed in Russia and many other countries, in March 2015.
