ABUJA, Nigeria (AP) — A girl who was seized from her school along with hundreds others during a raid by extremists ten years ago in northeastern Nigeria has been rescued together with her three children, the Nigerian army said Thursday.

Lydia Simon, who is five months pregnant, was rescued by Nigerian troops in the Gwoza council area of Borno state, where the 15-year insurgency by Islamic extremists is concentrated, according to a statement from the army.

The statement was accompanied by a picture of Simon and her children, who appear to be aged between 2 and 4. She is yet to be reunited with her family.

Simon was among 276 girls seized from their school in Nigeria’s Chibok village in April 2014 at the height of the extremist violence in the region. About 82 of them are still in captivity.

The first of a series of mass school kidnappings in the West African nation, the Chibok abduction shocked the world and triggered a global social media campaign tagged #BringBackOurGirls.

The Nigerian army did not say how she was freed other than that she was rescued in a hotspot known as Ngoshe, 130 kilometers (74 miles) north of the Borno state capital of Maiduguri.

Some Chibok parents and security analysts have said there is little evidence to show there is a special military operation to free the women. Those who returned in recent years were mostly found abandoned in the forests.

Some of the recently freed women were either raped by the insurgents or forced into marriages, according to Chioma Agwuegbo, an activist who was part of the #BringBackOurGirls campaign.

“We have heard their stories about the amount of trauma and violence they have faced. Somebody who was kidnapped 10 years ago is not returning as the same person,” Agwuegbo said.

Villagers in Chibok joined Simon’s family as they waited for when they would be allowed to see her. “The government has not told us anything (and) we are waiting for an official call,” said Yakubu Nkeki, chairman of the Chibok girls’ parents’ association.
