This is the official announcement:
The Department of Defense announced today the transfer of one detainee from the detention facility at Guantanamo Bay to the Government of Yemen.
On May 26, 2010, a U.S. District Court ordered the release of Mohammed Odaini from custody at Guantanamo Bay. As a result, the Department of Defense has transferred him to his native country. In accordance with Congressionally-mandated reporting requirements, the administration informed Congress of its intent to transfer Odaini at least 15 days before his transfer.
The suspension of Yemeni repatriations from Guantanamo remains in effect due to the security situation that exists there. However, the Administration respects the decisions of U.S. federal courts, which ordered the release of Odaini. As with all transfers, the U.S. Government will work with the Yemeni Government to the fullest extent possible to implement appropriate security measures.
Since 2002, more than 595 detainees have departed Guantanamo Bay for other destinations, including Albania, Algeria, Afghanistan, Australia, Bangladesh, Bahrain, Belgium, Bermuda, Chad, Denmark, Egypt, Georgia, France, Hungary, Iran, Iraq, Ireland, Italy, Jordan, Kuwait, Libya, Maldives, Mauritania, Morocco, Pakistan, Palau, Portugal, Russia, Saudi Arabia, Slovakia, Somalia, Spain, Sweden, Switzerland, Sudan, Tajikistan, Turkey, Uganda, United Kingdom and Yemen.Today, 180 detainees remain at Guantanamo Bay.
