US President Donald Trump posted an AI-generated video clip that he said was Iran’s oil hub Kharg Island being blown to smithereens, hours after the two countries traded attacks for the first time since July.

Axar.az reports, citing Reuters, it was not clear if Trump’s post was a threat to Kharg Island or if an attack was taking place.

Several hours after the post, there was no evidence Kharg had been attacked.

"Kharg Island being blown to smithereens!!! President DJT," Trump said on his Truth Social platform on Sunday, but gave no further details.

Reuters confirmed that an accompanying video clip showing dramatic explosions was most likely synthetically-generated, using software that detects AI-manipulated imagery.
