US President Donald Trump reportedly made a highly secretive departure from Turkey last month after American intelligence picked up information about a possible Iranian attack targeting the aircraft carrying him. According to two US officials cited by The New York Times, the threat involved a possible surface-to-air missile strike. The warning came as Trump was wrapping up his visit to Ankara for the NATO summit, prompting US security officials to take unusual measures to protect his movements. One piece of information pointed to a possible surface-to-air missile attack against the aircraft carrying the US president. Intelligence officials also believed Iranian operatives knew where Trump was staying in Ankara, including the floor of the building where he was lodged.
