US media report that President Donald Trump used a secret operation to travel from Turkey to the United Kingdom last month, involving a covert aircraft swap and the use of an airport food truck to move the president, in response to a credible threat from Iran, according to the Washington Post and New York Times, citing unnamed US officials. Shortly after Trump boarded Air Force One in front of cameras in Ankara, he secretly exited the plane using an airport food truck and transferred to a smaller US Air Force Boeing C-32A, while Air Force One continued its planned journey as a decoy. The operation followed intelligence about a threat to Trump's life that was assessed as credible, amid tensions with Iran, with which Turkey shares a border.
