Spanish legislators passed a resolution on Wednesday, describing the U.S. treatment of inmates at the Guantanamo military prison as "torture" and demanding an immediate closure of the prison.
The resolution, initiated by Spain's third largest party -- the United Left Party (IU) and approved by the Congress' Foreign Affairs Committee, was a response to reports of a triple suicide of prisoners held at the U.S. prison in Guantanamo, Cuba.
Cuba has opposed the U.S. Guantanamo naval base for decades and repeatedly condemned the treatment of prisoners held there, none of whom has received a trial.
IU leader Gaspar Llamazares said the Guantanamo prison was "an international disgrace" and "a Dante's inferno" where prisoners are held without either trial or charge.
But the right-wing Popular Party said that the accusations of serious human rights abuses committed by U.S. troops in Guantanamo discredit the progress made in the international fight against terrorism.
