In early 2002, at least 50 other surviving prisoners were transferred to Camp X-Ray at the newly constructed Guantanamo Bay detention camp at the U.S. Naval Base at Guantanamo Bay, Cuba. They were mostly Arabs, including 21 Saudis and nine Yemenis, but there were also some nationals from other countries such as Russian national Rasul Kudayev (from Kabardino-Balkaria), who had allegedly joined the Afghanistan-based Islamic Movement of Uzbekistan (IMU), and Abdul Jabar, an Uzbek member of the IMU. In 2004, after three years of detention without trial (at first at Camp X-Ray, until his identity was discovered), the U.S. citizen Yaser Esam Hamdi won a landmark U.S. Supreme Court case, "Hamdi v. Rumsfeld", which affirmed the right of U.S. citizens to "habeas corpus" and trial; he was released from United States custody without charges and was deported to his native Saudi Arabia.
