Iran has signaled it will respond to any further US military strikes by closing the Strait of Hormuz and targeting twice as many locations as in previous operations.
The warning, reported by multiple wire services, underscores the heightened volatility in the Persian Gulf as regional tensions continue to simmer.
The Strait of Hormuz remains closed to commercial shipping following an Iranian attack on a US naval base in Bahrain earlier this week.
This blockade represents a direct threat to global energy supplies, with approximately one-fifth of the world's oil passing through the narrow waterway.
The closure has already triggered significant repricing in energy markets, with Brent crude surging in recent sessions.
Iran's armed forces have vowed a "decisive and crushing" response to recent US military actions, while simultaneously rejecting any foreign interference in the Strait.
