SAN JUAN, Puerto Rico (AP) – The U.S. Justice Department has made public the names of 55 Guantanamo prisoners who have been approved for transfer to the custody of other countries. The information has been sought by human rights organizations.

Friday’s announcement reversed a 2009 decision and surprised several organizations that had filed FOIA requests seeking the names.

The U.S. previously did not publicize the names on the grounds that might “confuse, undermine, or jeopardize” diplomatic efforts with countries willing to accept detainees. But the government says in a new court filing that the successful resettlement of detainees no longer warrants such concerns.

ACLU attorney Zachary Katznelson says the release is a partial victory for transparency. He notes the U.S. did not release the names of 31 other detainees also approved for transfer.
