23 Afghans held at the US naval base at Guantanamo Bay for up to two and a half years were released in Kabul today.
Some complained of being unfairly detained and treated worse than animals.
The men were among 26 prisoners flown back from Cuba at the weekend having been detained without charge or representation.
Three Pakistanis travelled to their country after arriving with the group at the US base at Bagram north of Kabul on Monday night. No specific reason was given for the group's release.
In a statement, the Pentagon defended its continued detention of 610 people who it describes as 'enemy combatants' at the base.
The US says that, in all, 119 detainees have been released and 12 have been transferred for further detention.
