BBC World's weekend programme Panorama will report from Guantanamo Bay in south-east Cuba, where more than 600 men are being held by the US in a major war against terror operation. The show will be telecast this Saturday at 2.40 pm and a repeat will be shown at 8.40 pm on the same day and at 5.40 pm on Sunday.

Camp X-ray was established in January 2002 and the military considers those living inside the wire cages there to be "detained personnel" rather than prisoners.

After a six-month investigation, Panorama will uncover a picture of systematic arrest, interrogation and eventual trial by military commission at the camp. Besides going inside Camp Delta, the programme will travel to Asia, Europe and the US talking to those receiving and administering American justice.

In Afghanistan, Panorama will meet men who had been held for more than a year and then released. The American authorities maintain that detainees are treated humanely. However, in an exclusive interview, one person claims he was tortured, forced to kneel with his hands shackled above his head for long periods with a gun pointed at his head.

However, it also has the US military spokesman Colonel Rodney Davis countering, "It's not part of our culture, it's not part of what we do. We didn't come here to bring terror, we came here to stop terror."

Panorama will also follow the case of Moazzam Begg, one of the two British detainees who face the prospect of a trial after their detention at Camp Delta. His lawyer in Pakistan describes his client's arrest and swift removal into American custody in Afghanistan. His wife, Sally, adds, "If they think he's a terrorist, then they might as well say that I'm a terrorist, and they might as well take me to Guantanamo Bay, because I was there with him every step of the way and I know that he hasn't done anything wrong."
