U.S. President Donald Trump has threatened a military response against Iran after claiming that Iranian forces shot down a United States Apache helicopter during a patrol mission over the Strait of Hormuz.

In a post on his Truth Social platform on Tuesday, Trump said he had been informed by the U.S. military that an American helicopter was brought down by Iranian forces the previous night.

"I have just been informed by our Great Military that last night the Iranians shot down one of our highly sophisticated Apache Helicopters while patrolling over the Strait of Hormuz," Trump wrote.

"There were two pilots involved, both are safe and uninjured. Nevertheless, the United States must, of necessity, respond to this attack."
