Twenty-one of the schoolgirls kidnapped in 2014 by Boko Haram in Chibok, Nigeria, have been freed, the president’s spokesman has confirmed.
Garba Shehu said the release was “the outcome of negotiations between the administration and Islamist militants”.
Four imprisoned militants were reportedly freed in exchange.
Boko Haram seized more than 270 students from a school in Chibok, north-east Nigeria – an act that provoked international condemnation.
It sparked one of the biggest global social media campaigns, with tweeters using the hashtag #BringBackOurGirls.
President Muhammadu Buhari’s spokesman said on Twitter that the International Committee of the Red Cross (ICRC) and the Swiss government had acted as mediators in the talks with Boko Haram.
Mr Shehu added that negotiations were continuing.
The girls, who are due to arrive in Abuja, will be examined by a team of doctors and psychologists, Information Minister Lai Mohammed told journalists in the capital Abuja.
Mr Mohammed said the government was confident that this “credible first step” would lead to the eventual release of the remaining girls.
