Lagos, Nigeria (CNN) The 82 Chibok schoolgirls released in a swap between terrorist group Boko Haram and the Nigerian government have arrived in the capital city of Abuja, the government said Sunday.

The government freed five top Boko Haram commanders in the deal, said Sen. Shehu Sani, who was part of the negotiating effort.

"There's no price too high to pay," Sani said.

The released girls were received at the airport on behalf of President Muhammadu Buhari by Alhaji Abba Kyari, his chief of staff.

Chibok school girls recently freed from Boko Haram captivity are seen in Abuja, Nigeria, Sunday, May 7, 2017.

"Welcome our girls, welcome our sisters," Kyari said to the girls, who sat quietly in chairs. "We are very glad that you are back, and every Nigerian today must be forgetting every other hardship and suffering, because this is a very joyous moment. Welcome, welcome, welcome."
