SAN JUAN, Puerto Rico AP – A Yemeni detainee at Guantanamo Bay has died of an apparent suicide, U.S. military officials said Tuesday. His is the fifth apparent suicide at the offshore U.S. prison, which President Barack Obama hopes to close by January.

The Joint Task Force that runs the U.S. prison in Cuba said guards conducting a routine check found Muhammad Ahmad Abdallah Salih unresponsive and not breathing in his cell Monday night.
