The US military conducted its largest oil escort through the Strait of Hormuz as Iran warned the strategic waterway will remain closed without sanction relief.

The United States military has completed its largest crude oil escort through the Strait of Hormuz since conflict broke out, deploying air, maritime, and space assets to protect commercial shipping. Iranian forces retaliated by launching sea mines into critical maritime corridors, prompting American strikes against military positions on Larak Island.

Tehran maintained that the strategic waterway "will not be opened" until Washington complies with a memorandum demanding an end to port blockades, the lifting of petroleum sanctions, the unfreezing of Iranian assets, and the cessation of military threats. Prior to the outbreak of hostilities, approximately 20 million barrels of crude passed through the passage daily. Observers warn that both sides are facing a closing window to exert tactical pressure, heightening the potential for further military escalation.
