A Yemeni detainee at the Guantanamo Bay prison camp has died in an "apparent suicide," US military officials say.
Guards found 31-year-old Muhammad Ahmad Abdallah Saleh unresponsive and not breathing in his cell Monday night, the military said.
"Medical personnel were immediately summoned by the guard force. After extensive lifesaving measures had been exhausted, the detainee was pronounced dead by a physician," the US military said in a statement on Tuesday.
Saleh is the fifth detainee held at the Guantanamo detention centre to "commit suicide".
The Yemeni prisoner, known as al-Hanashi, had been held without charge at the camp since February 2002.

Saleh had been on hunger strikes in the past to protest his detention, but was not among long-term hunger strikers currently being force-fed at the camp, a Guantanamo spokesman said.
An autopsy was due to be carried out and a "cultural adviser" was ensuring that his body was being treated in accordance with Islamic traditions, the military said.
"Upon completion of the autopsy, the remains will be prepared for repatriation to Yemen," the military said.
Since the detention camp opened in January 2002, four other prisoners have committed suicide by hanging themselves in their cells - three on the same day in June 2006 and one in May 2007.
Another prisoner died of colorectal cancer in December 2007.
The White House is still considering what to do with the 239 remaining captives held at Guantanamo, who include nearly 100 Yemenis.
Barack Obama, the US president, has ordered the camp be closed by January 2010.
