Saudi Arabia has freed 18 former Guantanamo Bay detainees after they completed their jail sentences, the Interior Ministry said on Tuesday. The men were among 28 Saudi nationals and one resident handed over this year by the United States from the Guantanamo Bay naval base in Cuba, it said. The Muslim kingdom had released 11 of the men earlier this month. “The remainder, numbering 18 convicts, were freed ... after the necessary conditions were fulfilled,” the official Saudi Press Agency said, quoting Interior Ministry spokesman Mansour bin Sultan al-Turki. Saudi Arabia said it would continue efforts to secure the return of other Saudi citizens. It did not say how many Saudis remained in US custody at the controversial prison camp. Many of the men held at Guantanamo Bay were captured in Afghanistan in the US-led war to oust the Taliban after the Sept 11 attacks.
