A father of two of the 276 kidnapped Nigerian girls is asking the government not to comply with Boko Haram's demand to free prisoners.
The militants released a video Monday telling Nigerian officials that the schoolgirls will be released when imprisoned Boko Haram members are set free.
The father urged the government not to negotiate with the extremists.
"It's not right. They'll do it again," he told Sky News.
On April 14, Boko Haram invaded an all-girls school in Chibok, Nigeria and forced over 200 girls into trucks. The militants then drove off into the forest. 53 abducted girls were able to escape.
A second kidnapping occurred on May 4 when at least eight girls were taken from Warabe, Nigeria. Witnesses say Boko Haram went door to door, taking girls and assaulting anyone who tried to intervene.
On May 11, Boko Haram leader Abubakar Shekau displayed over 100 girls in a video that derided search efforts and called for the release of his "brethren."
"It is now four years or five years that you arrested our brethren and they are still in your prison," Shekau said.
"You are doing many things [to them]. And now you are talking about these girls. We will never release them until after you release our brethren."
In the video, the girls are praying and wearing chadors—a single cloth covering the head and body that is worn by some Muslim women.
Shekau said that the children have been converted to Islam.
Officials are not ruling out the possibility of releasing prisoners to bring the girls home.
"The government of Nigeria is considering all options towards freeing the girls and reuniting them with their parents," Mike Omeri, director general of the National Orientation Agency, said in a Monday news conference.
