Iran has launched a new wave of strikes against US naval supply lines in the Persian Gulf, marking a sharp escalation in the ongoing standoff over the Strait of Hormuz.

The Islamic Revolutionary Guard Corps (IRGC) executed the attacks as part of a broader campaign to assert control over the critical waterway, reversing the brief easing of tensions that had seen oil prices retreat earlier in the week.

The development immediately reignited supply disruption fears among energy traders.

Brent crude futures surged on the news, as markets repriced the risk of a prolonged closure of the Strait of Hormuz, which handles roughly a fifth of global oil consumption.

The attack on logistical targets suggests Tehran is moving beyond rhetorical threats to tangible military pressure on Western naval presence in the region.

This escalation follows President Donald Trump's declaration that US forces would bomb Iran, a statement that had already gripped global markets.

The US has since launched a fresh wave of military strikes in response to Tehran's decision to close the Strait to shipping.
