HIV-positive Egyptian men are tortured and chained to hospital beds while awaiting unfair homosexuality trials, a human rights group has claimed.

Human Rights Watch (HRW) decried the "ignorance and injustice" of a case in which a group of arrested men were given HIV tests without their consent.

They were also subjected to anal tests to "prove" their homosexual conduct.

Two of the men tested HIV-positive and are now handcuffed to hospital beds for 23 hours a day, HRW said.

"These men have been subjected to anal examination without their consent which amounts to torture," Gasser Abdel-Razek, HRW's acting director of regional relations in the Middle East, told the BBC on Wednesday.

"Egypt should release the men unconditionally and put a system in place that does not deal with HIV-positive individuals as criminals but as patients who require medical care and attention."

Egypt's Interior Ministry had no immediate comment on the case...

Their lawyers claimed the prosecution had produced no evidence against the defendants, who pleaded not guilty.

While not explicitly referred to in Egypt's legal code, homosexuality can be punished under several different laws covering obscenity, prostitution and debauchery...
