A Nigerian intelligence officer and a camp official say the 275 women, girls and children rescued from Boko Haram have been taken into military custody amid suspicions that some are aiding the Islamic extremists.

They say soldiers took the group Tuesday from the Malkohi northeastern refugee camp to the airport where a military plane flew them to an unknown destination. Spokesman Sani Datti of the National Emergency Management Agency says soldiers did remove the group but he said he has no other information about an "entirely military affair."

An intelligence officer told The Associated Press the move follows fears that some women were communicating at night with Boko Haram militants. He and the camp official requested anonymity because the affair is sensitive.
