US intelligence assessed that Iranian operatives had tracked Donald Trump in Ankara, prompting a covert aircraft switch before his departure. The operation stayed hidden for weeks and stood out because the deception continued even after he had left the immediate risk zone.

Two US officials familiar with the intelligence told the New York Times that US agencies had received multiple streams of information pointing to a specific threat involving a surface-to-air missile targeting Air Force One.
