This raises the question of what has been given in return for the girls' release; the Nigerian government held several Boko Haram commanders who could have been handed over as barter. "So in the early hours of today, they did return the girls and majority went to their parents", he said.
The girls were said to have been attended to at the Dapchi General hospital before they were conveyed in some mini buses and coaster luxury buses escorted by heavy military personnel.
Nigeria's government celebrated the girls' release.
"If the immediate past Peoples Democratic Party (PDP) administration had responded with the similar alacrity, the Chibok schoolgirls would have been released or rescued", he said.
The Minister said the girls were released around 3 a.m. through back-channel efforts and with the help of some friends of the country, and that it was unconditional.
Another resident of Dapchi said five girls were reportedly trampled to death as they were being driven away in overcrowded trucks.

The school girls were abducted on February 19 by Boko Haram insurgents.
The spokesman added that government would ultimately rehabilitate and reunite the girls with their families and loved ones when they were eventually rescued.
The organization also "urges the authorities to urgently establish a judicial commission of inquiry to conduct a thorough, impartial and effective investigation into allegations of complicity against some members of the military and security forces in the abduction of the girls". "Boko Haram men brought back the girls this morning".
Boko Haram Islamists have threatened: "don't ever put your daughters in school again" as they set free almost all of the 110 kidnapped Nigerian schoolgirls after seizing them in Dapchi last month.
He said the students were brought back in nine vehicles and dropped outside the school at about 8am by the insurgents. Boko Haram received millions of euros for the release of some of the Chibok girls a year ago. "But what I have been told is that 91 girls and one boy have been documented".
He called on the worldwide community to support the Federal Government to secure the release of the girls and others still in captivity.
