Shettima said in a statement in Maiduguri that the release had proved President Muhammadu Buhari’s sincerity in ending the Boko Haram insurgency.
The statement was signed by the governor’s Special Adviser on Communication, Malam Isa Gusau, in Maiduguri.
“If any Nigerian had doubts about the sincerity and commitment of President Muhammadu Buhari to the rescue of our precious daughters abducted by the Boko Haram insurgents at Government Secondary School, Chibok, on April 14, 2014,…such doubts should be eliminated by the success of the negotiation that led to the release of 21 Chibok schoolgirls.
“As people of Borno State, troubled by the deaths and destructions of Boko Haram insurgency, one of our major sources of strength since May 29, 2015, has been the undiluted sincerity we saw in President Muhammadu Buhari based on his administration’s absolutely genuine commitment toward recovering our schoolgirls.
“And thousands of other women and children held in captivity as well as ending the insurgency in order to secure the lives of our citizens and make way for reconstruction, resettlement and other development programmes and projects.
“We had faith in Buhari from the very day he took off as President,’’ the governor said.
Shettima said the steps Buhari kept taking in dealing with the insurgency had continuously proved his sincerity.
