A schoolgirl who was abducted by Nigeria’s militant Islamists in 2014 has escaped from captivity, presidential spokesman, Femi Adesina, has told the BBC.
The girl was found by government troops while she was escaping, Mr Adesina said, without giving details.
She was among 276 girls seized by Boko Haram from north-eastern Chibok town in 2014, sparking global outrage.
Government officials in Borno State, where the girls were abducted, could not immediately corroborate the claims of the Nigeria presidency.
A total of 103 of the girls have been released so far, including 82 earlier this month in a prisoner swap.
The 82 girls, who met President Muhammadu Buhari on May 7, are expected to be reunited with their families later this week.
They were escorted to a reception in Abuja by armed soldiers, after a check-up at a medical centre.
“I cannot express in a few words how happy I am to welcome our dear girls back to freedom,” President Buhari told the girls in Abuja, according to his office.
“On behalf of all Nigerians, I will like to share my joy with you.”
