GUANTANAMO BAY, Cuba - Human rights observers at Guantanamo naval base are celebrating President Barack Obama's order to close the detention centre within a year, while a prosecutor holds out hope war-crimes trials will resume.
Stacy Sullivan of New York-based Human Rights Watch says her current trip will likely be the last.
She says she hopes that some day the prison will become a museum "memorializing a really shameful chapter in American history."
Defence lawyer Brian Mizer - a Navy lieutenant commander - calls the order "a great day for America."
But prosecutor Jeff Groharing says he hopes the military trials will resume.
The marine major says victims of terrorist attacks "need justice to be done."
