Inside Camp Delta

Camp Delta is unlike any other American prison, civilian or military. The military says the 660 prisoners there are considered dangerous enemies in the war on terror.

The prison is on a bluff overlooking the Caribbean, an isolated corner of the remote U.S. Naval Base at Guantanamo Bay.

Security is tight - razor wire, guard towers and and searchlights control the perimeter while gunboats patrol the waters below.

From the first day Camp Delta opened, the main goal has been to get prisoners to talk, and to tell everything they know about terrorists and their organizations.

The prisoners, from 42 different countries, were captured in Afghanistan, and flown to Cuba in January 2002. Since then, they've been kept incommunicado and out of sight.

A typical 8x6 cell is similar to prison cells in the U.S. There are 48 cells per high-security cellblock, about 1,000 cells in all - and plans to build more.

Standard-issue clothing and toiletries are given to each detainee.

Items such as checkers, cards and even cups are given to detainees on good behavior. An arrow pointing toward Mecca is also a reminder of just how far the prisoners are away from home.

Each cell also comes equipped with a Koran and prayer beads. And each day begins with the Muslim call to prayer over the camp's PA system.

Best-behaved prisoners get 30 minutes a day in the exercise yard. There are soccer balls, and prisoners are able to do different types of exercises, like running. But the Army says that some of them just come and sit.

Camp Iguana, named after the reptiles that run loose all over the base, is where the three youngest prisoners, between the ages of 13 and 15, are kept. The Army says they are "de-briefed," not interrogated.

At the health center, the Army says prisoners get the same level of medical treatment as soldiers.

Detainees who provide useful information are rewarded with a move to a special camp, where they live communally, but under constant surveillance.

The Pentagon says it will keep prisoners in Guantanamo until the war on terror is won. But inside Camp Delta, both prisoners and guards know that could be a long time.
