US President Donald Trump announced that the US is launching the "MOST CRUSHING ECONOMIC OPERATION EVER TAKEN AGAINST ANY COUNTRY".

"This will be Economic Warfare and Isolation on an unprecedented scale. Their navy is gone, their air force is destroyed, their military factories are now rubble, their currency is worthless, and their country is hanging by a thread," he said in a post on his platform Truth Social.

The US president also warned that any country supporting Tehran in any way will face "TREMENDOUS Economic Consequences", but did not make mentions of a specific country or what actions Washington is expected to take.

"This will be an ECONOMIC D-DAY, and we need all of our Allies to stand with the United States of America to isolate, and defeat, the Iran threat," he added.

"These maniacs are on the ropes, and these HISTORIC MEASURES will cripple them and their ability to project terror worldwide. IRAN WILL NEVER HAVE A NUCLEAR WEAPON."
