A former driver for Osama bin Laden was transferred from Guantanamo Bay to his homeland of Yemen to serve out the remaining 32 days of his sentence, the Pentagon said Tuesday. Salim Hamdan, the first man to go before a US war crimes trial since the end of World War II, was flown from the US Navy base in Cuba to Yemen. Hamdan was convicted on Aug. 6 of providing material support to terrorism, and the military said it could keep him locked up indefinitely if it considered him to be a continued threat. Instead, he was sent home early. A Pentagon official, speaking on the condition of anonymity because he was not authorized to discuss the matter, said the decision was made by the White House.
