US military authorities plan to transfer about a third of the detainees at the Guantanamo "war on terror" camp to their home countries after a review carried out over the past year, a US military officer said.The Defense Department has concluded that 119 detainees did not need to be held at the US naval base in Guantanamo Bay, Cuba and would be taken into custody by countries where they hold citizenship, Navy Captain Tom Quinn told reporters here on Tuesday. Another 14 detainees would be released outright because they no longer presented a threat to the United States and offered no "intelligence value," Quinn said.
