Three Guantanamo Bay detainees hanged themselves with nooses made of sheets and clothes, the commander of the detention center said Saturday. They were the first reported deaths among the hundreds of men held at the base in Cuba some of them for up to 4 1/2 years and without charge. Two men from Saudi Arabia and one from Yemen were found "unresponsive and not breathing in their cells" early Saturday, according to a statement from the Miami-based U.S. Southern Command, which has jurisdiction over the prison. Attempts were made to revive the prisoners, but they failed. "They hung themselves with fabricated nooses made out of clothes and bed sheets," Navy Rear Adm. Harry Harris told reporters in a conference call from the U.S. base in southeastern Cuba. Pentagon officials said the three men were in Camp 1, the highest maximum security prison at Guantanamo, and that none of them had tried to commit suicide before. That camp was also the location where two detainees tried to commit suicide in mid-May, when a riot broke out at the facility. The two men, who took overdoses of an anti-anxiety medication they hoarded, were found and received medical treatment and were recovering.
