I was tortured at Guantanamo

Mehdi Ghezali, the son of an Algerian-born immigrant, told Swedish media in interviews published or aired Wednesday that he was interrogated almost every day at the US naval base on Cuban soil.

The 25-year-old man, who was arrested in Pakistan where he says he was studying Islam, was released on July 8 after pressure from Sweden.

Ghezali told Dagens Nyheter daily and Swedish public radio he had cooperated for the first six months but stopped talking when his interrogators kept asking the same questions.

In April the military changed their tactics, he said.

"They put me in the interrogation room and used it as a refrigerator. They set the temperature to minus degrees so it was terribly cold and one had to freeze there for many hours -- 12 to 14 hours one had to sit there, chained," he said, adding that he had partially lost the feeling in one foot since then.

Ghezali said he was also deprived of sleep, chained for long periods in painful positions, and exposed to bright flashes of light in a darkened room and loud music and noise.
