Nigeria’s presidency has confirmed the release of 21 Chibok girls
kidnapped by Boko Haram Islamists in 2014. And also said the Chibok
girls were exchanged for four Boko Haram prisoners in Banki.

“The release of the girls…is the outcome of negotiations between the
administration and the Boko Haram brokered by the International Red
Cross and the Swiss government,” a presidency statement said. “The
negotiations will continue.”
Around 270 girls were taken from their school in Chibok in April 2014.
Dozens escaped in the initial melee, but more than 200 are still
missing.
