Version 1about 2 months ago

What changed: The story was updated to include President Trump's statement that the blockade remains in full force, signaling a hardline U.S. stance against Iran's maritime leverage.

The crisis in the Strait of Hormuz has escalated into kinetic military engagement after IRGC gunboats opened fire on an oil tanker 20 nautical miles northeast of Oman without a prior VHF challenge. This escalation follows the re-closure of the Strait on Saturday after a brief reopening on Friday, forcing approximately 20 commercial vessels to turn back toward Omani waters. Maritime tracking confirmed that tankers 'Minerva Evropi' and 'Nissos Keros' diverted their courses, while the 'Sanmar Herald' reportedly continued via an Iran-sanctioned route. Tehran maintains that the strategic chokepoint will remain shut until President Donald Trump lifts the economic blockade, a demand the U.S. administration has met with continued 'full force' pressure. These developments have significantly heightened geopolitical risk premiums as markets face immediate disruptions to global crude oil flows and maritime security.
