Addressing the abducted, now freed schoolgirls, Buhari said:
"My dear children. This is a happy moment for me and for all Nigerians. I welcome you back to freedom. It is a moment your parents, the Nation and the International Community have been eagerly waiting for, since your abduction on 14th April 2014.
"We must from the onset, thank Almighty God for this day that 21 of the Chibok girls have again breathed the air of freedom and are reunited with their parents. We are equally prayerful, that God in his infinite mercies and benevolence, will see to it that the girls remaining in captivity will be freed and returned to us soonest.
"All Nigerians recall, sadly the night of 14th April 2014, 276 young female Nigerian students were abducted from the Government Secondary School in Chibok Borno State by the Boko Haram.
"Fortunately, 57 of the kidnapped school girls were able to escape, leaving 219 in captivity. One of the abducted girls, Amina Ali was found in May 2016. And today we are here celebrating the freedom and return of another 21 girls that regained freedom on Thursday 13th October. We are equally as hopeful as we are praying, that the remaining girls will be freed and returned to us without further delay.
"The release of these 21 girls followed a series of negotiations between Government and the Boko Haram group, brokered by our friends both local and International. Since this Administration assumed office, we have been working towards the safe release of the girls. The Nigerian DSS, Military and other Security Agencies have spared no effort to secure our girls. These 21 girls are the manifestation of our doggedness and commitments to the release and return of the Chibok girls."
