Here is an astounding example of the propaganda being fed to the Arab world, at Bahrain’s Gulf Daily News: I am losing my mind behind these horrible prison walls.

Mr Al Dossary describes being brutally beaten by up to eight guards and being forced to walk on broken glass, then having his face pushed down into it.

He describes an incident in 2002 reported in the GDN last week, in which he was stripped naked then shackled to the floor on his back, while a female interrogator squatted nude over him and smeared him with her menstrual blood.

In another incident, he alleges he was forced to watch a man and woman having sex, before being offered sex with the woman if he co-operated with interrogators.

The list of alleged incidents of abuse appears endless and Mr Al Dossary,who is thought to have attempted suicide more than once, says even the memory of them is torture.

“As I recall these incidents, I feel that I am losing my mind and my body is shivering, with a painful feeling deep inside me,” he writes.

“Did I really live through these incidents? The images of those hours of torture will haunt me forever. The worst part was the psychological torture, which is far worse than physical torture. Physical torture will only bring me closer to God, but psychological torture devastated my soul. Due to the severe psychological pressure on me, I can’t even stand. Even tears that normally calm the soul have failed me.”

Mr Al Dossary says conditions at Guantanamo are so bad that even some of the guards are disgusted.

“I once overheard one of the American soldiers say that he would not even allow his dog live in a place like this,” he writes. “He said his dog back in the US lived in a place a hundred times better than here.”

His anguish is evident in his words, though the handwriting is intricate and tidy.

“I write these words from behind the walls of this horrible detention centre,” writes the 30-year-old, who has an 11-year-old daughter growing up without him.
