The accusations against a woman who was rescued from Boko Haram abductors came from some of her fellow former captives during a group counseling session.

Why had she received preferential treatment and better food while they were held? Wasn't she married to a fighter from the Islamic extremist group?

As scores of young Nigerian women and children are rescued from the clutches of Boko Haram, they face suspicions that they may still be in contact with their former captors.

These fears apparently have led to an entire group of 275 women and girls rescued from the extremists last month being forced to remain in custody — held this time by the Nigerian military.

After creating havoc in northeastern Nigeria for years, Boko Haram militants have suffered a series of defeats this year from an offensive by better-equipped Nigerian troops bolstered by forces from neighboring Chad, Niger and Cameroon.

As the militants retreat, the many captives they seized are being rescued, but that doesn't mean their ordeal is over. Many remain traumatized by their harsh captivity — including rape, sexual slavery and beatings — as well as suspicions that some cooperated with their captors and may still support them.

In counseling sessions at the Malkohi Camp outside the northeastern city of Yola, witnesses described some of the women accusing another one of having ties to their former Boko Haram captors.

Relations between soldiers guarding the camp and some of the rescued women had been tense after a fracas witnessed May 17 by a reporter in which a soldier falsely claimed that one of the women tried to grab his gun and told him she was a Boko Haram member.

On Tuesday, soldiers took the group of more than 200 children — almost all younger than 5 — and 67 girls and women from the camp, the National Emergency Management Agency has confirmed.

Agency spokesman Sani Datti said he had no other information about the incident because it was an "entirely military affair."

The group was put on a military plane and flown to an unknown destination, possibly the capital of Abuja, a camp official and a military intelligence officer told The Associated Press on condition of anonymity because they were not authorized to talk to the media about the issue.

Nigerian military and intelligence spokesmen did not immediately respond to questions about the group. Their move from the camp only became known after an AP story about the heroism of one teenager, Binta Ibrahim, prompted two readers to send $500 to her. An AP reporter who went to the camp to find out how to get the money to her discovered the group was no longer there.

It is not known how many girls, women and children have been kidnapped by Boko Haram over the years. Many have escaped or been released since the multinational offensive chased the militants from towns in the northeast. Some of the girls and women were used by the militants as suicide bombers, sending them into crowded markets and bus stations.

The president of the International Committee of the Red Cross, Peter Maurer, expressed alarm Thursday at the scale of the humanitarian needs and "the horrific mental and physical scars" that the violence by Boko Haram has left on the people of northeast Nigeria.

"Whole communities have fled their villages and endured unimaginable suffering. Traumatized people, without homes, belongings, income and education for their children — what does the future hold for them?" Maurer said, adding that the needs were far beyond the capacity of his Geneva-based organization and demand serious international attention.

Boko Haram abducted nearly 300 schoolgirls from the northeastern town of Chibok in April 2014. Dozens escaped, but 219 remain missing. The plight of the schoolgirls, who have become known as "the Chibok girls," sparked international outrage and a campaign for their release under the hashtag #BringBackOurGirls.

A counselor who worked with the rescued group at Malkohi said they told him that Christians among the captives had been forced by Boko Haram to convert to Islam, and some were forced to marry fighters. At least 18 of them are pregnant.

One 22-year-old told him she was paid a dowry of 500 naira — the equivalent of $2.30 — to marry an insurgent.

Others said they were treated like "slaves," forced to do domestic work and whipped if they disobeyed. One showed the counselor her back, which was covered with scars.

But the counselor said the only person who had openly supported Boko Haram was a 4-year-old boy whose mother and father belonged to the group. He said he feared for the boy's life and had had officials remove him from the camp.

The child openly boasted that his father would slit people's throats and gun them down, saying that the killing of infidels was the work of God, according to the counselor, who spoke on condition of anonymity because he was not authorized to talk to reporters about the sensitive subject.

He said the entire group was traumatized and all the rescued children were badly malnourished. A 2-year-old died May 3, the day after the group reached the safety of the camp, he added.

Their rescue was a success story for Nigeria's military, which last month reported freeing about 700 girls, women and children from Boko Haram captivity in an ongoing offensive on the insurgents' Sambisa Forest stronghold.

When they came to the camp, those rescued told AP heartbreaking stories of their captivity and the trauma of their rescue. Boko Haram fighters stoned several women to death when they refused to flee with them as the military advanced on their position. Others were crushed accidentally by an armored military vehicle, and three women were killed by a land mine.

Binta Ibrahim, the 16-year-old praised for her heroism, told how she rescued three children between the ages of 2 and 4, cared for them during a year of captivity under Boko Haram, and brought them to the safety of the refugee camp.

At one point, Ibrahim said, she had to walk for two days with the children — one strapped to her front and the other two clinging to her back.

Samantha Power, the U.S. ambassador to the United Nations, was so moved by Ibrahim's story that she cited her during a commencement address at the University of Pennsylvania this week.

"Binta is a Muslim. The three kids she saved are Christian. Tell me a more powerful rejection of Boko Haram's perversion of Islam than Binta's love for those kids," Power said.

Now, the fate of Ibrahim and others at the camp is uncertain.

The Nigerian military and intelligence services have faced criticism over their treatment of the thousands of suspected Boko Haram members or supporters that they have detained over the nearly 6-year-old insurgency.

More than 3,000 male detainees died during a period of a few months at Giwa Barracks in the northeastern city of Maiduguri in 2013, according to an AP investigation. Amnesty International said some starved to death, some suffocated in overcrowded conditions, and some were simply taken out and shot.
