Dead Guantanamo prisoner had U.S. military training
'The Guantanamo prisoner who died in his cell this week was a Saudi army veteran who trained with U.S. soldiers before going to fight for the Taliban in Afghanistan, military records show.
The man, described by the U.S. military on Thursday as a mid-level al Qaeda operative, apparently committed suicide on Wednesday at the prison camp for foreign terrorism suspects at the U.S. naval base in Guantanamo Bay, Cuba.'
