Trump says U.S. Navy destroyed 'provocative and hostile' Iranian drone that flew within 1,000 yards and ignored warnings to retreat

President Donald Trump said Thursday that the U.S. Navy has destroyed a drone controlled by Iran, calling the unmanned vehicle's approach of an American ship a 'provocative and hostile' act.

The conflict came in the Strait of Hormuz, the only shipping lane between the Persian Gulf and the open ocean. About one-fifth of the world's oil passes through it.

Trump said at the White House that the USS Boxer, a Wasp-class amphibious assault ship, 'took defensive action' after the drone strayed to within 1,000 yards.

'The drone was immediately destroyed,' he said, after its operators ignored 'multiple calls to stand down.'
