Iran has declared the Strait of Hormuz an inviolable "red line," escalating tensions with the United States as the confrontation widens beyond military targets. The warning signals that Tehran views any threat to the strategic waterway as a direct challenge, especially because of its importance to global oil shipments.

According to the report, Iran also said it would respond by striking regional infrastructure if President Donald Trump follows through on threats to attack Iranian infrastructure. That message points to a broader retaliation strategy, suggesting any direct strike could trigger consequences across the wider Gulf region.

The standoff comes as the US is said to be targeting Iran's military capabilities while reimposing a naval blockade. Together, those moves raise the risk of a deeper regional crisis, with energy routes and critical facilities increasingly drawn into the dispute.

With the Strait of Hormuz at the center of the warning, markets and governments are likely to watch closely for any disruption to shipping or signs of further military escalation. Iran's position underscores how quickly the conflict could affect both regional security and the flow of oil through one of the world's most sensitive maritime corridors.
