The human rights group Amnesty International has issued a report critical of the U.S. detention center operated at Guantanamo Bay, Cuba.
In the report released Monday Amnesty said 500 men from 35 countries are being held at Guantanamo and that some have conducted hunger strikes or attempted suicide. It also cites hardships on the detainees' families.
The group said U.S. authorities should release those who are not going to be charged with internationally recognized criminal offenses.
Amnesty also called on the U.S. to publish a list of those detained at Guantanamo and elsewhere, to close Guantanamo, and to investigate allegations of ill-treatment of detainees.
President Bush has said the detention center is a necessary part of protecting the American people and that Guantanamo's prisoners are treated humanely.
