The Pentagon in the US says that reviews into the status of the detainees at Guantanamo Bay could begin as soon as next week.
The move follows a Supreme Court ruling enabling inmates to challenge their detention through the US legal system.
The Pentagon says the review process could lead to some prisoner releases.
The detainees, which total almost 600, have now been notified of their rights, but it is still unclear how they will get access to lawyers.
