The girls were freed on Saturday in exchange for the release of five Boko Haram suspects

Eighty-two Chibok schoolgirls seized three years ago by Boko Haram have been freed in exchange for detained suspects with the extremist group, Nigeria’s government announced yesterday, in the largest release negotiated yet in the battle to save nearly 300 girls whose mass abduction exposed the mounting threat posed by the Islamic State-linked fighters.

The released schoolgirls met with President Muhammadu Buhari on Sunday evening. Photos released by the government showed the president standing and addressing the Chibok schoolgirls at his official residence Sunday evening, a day after their release.

“The president was delighted to receive them and he promised that all that is needed to be done to reintegrate them into the society will be done,” adviser Femi Adesina said. “He promised that the presidency will personally supervise their rehabilitation.”

The young women have been handed over to government officials who will supervise their re-entry into society, Adesina said. The International Committee of the Red Cross, which helped negotiate the girls’ release along with the Swiss government, said they would be reunited with their families soon.

The April 2014 abduction by Boko Haram brought the extremist group’s rampage in northern Nigeria to world attention and, for families of the schoolgirls, began years marked with heartbreak.

Some relatives did not live long enough to see their daughters released. Many of the captive girls, most of them Christians, were forced to marry their captors and give birth to children in remote forest hideouts without ever knowing if they would see their parents again. It is feared that other girls were strapped with explosives and sent on missions as suicide bombers.

As word of the latest release emerged, long-suffering family members said they were eagerly awaiting a list of names and “our hopes and expectations are high.”

Before Saturday’s release, 195 of the girls had remained captive. Now 113 of the girls remain unaccounted for.

A Nigerian military official with direct knowledge of the rescue operation said the freed girls were found near the town of Banki in Borno state near Cameroon.

Boko Haram remains active in that area. On Friday, the United States and Britain issued warnings that the extremist group was actively planning to kidnap foreigners in an area of Borno state “along the Kumshe-Banki axis.”

The 276 schoolgirls kidnapped from Chibok in 2014 are among thousands of people abducted by Boko Haram over the years.

The mass abduction shocked the world, sparking a global #Bringbackourgirls campaign supported by former US first lady Michelle Obama and other celebrities. It has put tremendous pressure on Nigeria’s government to counter the extremist group, which has roamed large parts of the north and into neighboring countries.

“This is a very, very exciting news for us that we have over 80 of our girls coming back again,” Bukky Shonibare with the #BringBackOurGirls campaign told Sky TV. “Their life in captivity has been one that depicts suffering, it depicts the fact that they have been starved, abused, and as we have seen before some of those girls have come back with children, and some of them have also come back with news of how they have been sexually abused.”

Buhari late last year announced Boko Haram had been “crushed,” but the group continues to carry out attacks in northern Nigeria and neighboring countries. Its insurgency has killed more than 20,000 people and driven 2.6 million from their homes, with millions facing starvation.
