Goa, April 8 -- U.S. President Donald Trump escalated pressure on Iran Wednesday, vowing 50% tariffs on any nation arming the regime.

"Any country supplying military weapons to Iran will be immediately tariffed," Trump declared on Truth Social. The penalty hits "any and all goods sold to America-50%, effective immediately." No exemptions.

The shock move follows the fragile U.S.-Iran ceasefire, amid Strait of Hormuz tensions. Trump aims to choke Tehran's supply lines post-Pakistan-mediated truce.

Global markets jittery-oil spiked 3%. Allies like India watch closely; China, Russia face spotlight as alleged suppliers.

"This ends the free ride," Trump added. Critics slam economic fallout; supporters hail tough stance.
