By Phil Stewart and David LawderWASHINGTON, Aug 30 (Reuters) - Iran's energy hub of Kharg Island is being blown to smithereens, U.S. President Donald Trump said on Sunday in a one-line social media post accompanied by an AI-generated video clip. There was no other evidence that the Iranian energy hub was under attack. The White House and the U.S. Defense Department did not immediately respond to Reuters requests for comment outside regular business hours.There was no immediate response to Trump's post on Iranian media.

Iran responded to an earlier US attack on rocket launchers on its island of Larak, about 660km east of Kharg, with an assault on two US bases in Jordan, Iranian media said.

The president’s post comes as the U.S. military carried out its first major attack against Iranian forces in the Strait of Hormuz this month.
