Havana, June 23 (RHC) The United States spent over $5b dollars during the past 10 years in maintaining the US Naval Base in its occupied Cuban territory of Guantanamo, where Washington has had a prison camp since 2002.

According to USA Today, for the fiscal year 2015, the Pentagon has allocated an extra 149 million dollars for operations in the prison camp, where 150 persons are still held captive, while other additional sums will be used in overseas military missions.

Some 780 detainees have been transferred to other nations, including five Taliban members swapped for US sergeant Bowe Bergdhal, who was arrested by the afghan rebels since 2009, PL news reported.

Attorney general Eric Holder said that the Guantanamo prison camp will be a permanent site, given the way the prison and facilities have been built, for holding detainees before trial, USA today said, as quoted by PL news agency.

When president Obama assumed his first term of office in 2009, he signed an executive order to shut down the prison in less than a year, but the center is still working.

Many denunciations point at the use of cruel techniques, such as the enclosing of prisoners naked under very low temperatures, distortion of their sleep and exhausting interrogation sessions.
