[JURIST] AP is reporting that according to his lawyer, the plane carrying Yaser Esam Hamdi has arrived in Saudi Arabia. A US citizen captured by American forces in Afghanistan, designated an "enemy combatant", held without charge by the Defense Department for over two years, and finally the subject of a lawsuit that went all the way to the US Supreme Court, Hamdi was freed to go to Saudi Arabia under a deal reached last month [settlement agreement]. Hamdi also holds Saudi citizenship, but his transit there was delayed while US and Saudi officials negotiated over how US conditions on his mobility would be enforced.
UPDATE: An AP story on Hamdi's release and deportation is now available here. A timeline of the litigation in his case is available here from the US District Court for the Eastern District of Virginia, which notes that "litigation involving Yaser Hamdi has included three separate cases, five decisions by the US. Court of Appeals for the Fourth Circuit, and a ruling by the US Supreme Court." Previous reports on Hamdi in JURIST's Paper Chase are available here.
UPDATE-2: A US Statement Department press statement on Hamdi's release is online here.
