The Strait of Hormuz remains a flashpoint for global energy markets after Iranian state media reported fresh explosions near the narrow waterway on Monday.
The blasts, reported by the Mehr news agency, add to a growing list of incidents threatening one of the world's most vital shipping corridors.
The development underscores the persistent volatility in the region, where commercial vessels face ongoing risks from military activity.
Earlier reports indicated that a Qatari liquefied natural gas (LNG) tanker was at risk after Iran fired missiles at vessels in the strait overnight.
The recurring nature of these incidents highlights the fragility of energy supply chains dependent on this chokepoint.
Markets have already begun to price in the elevated risk, with Brent crude climbing as traders assess the potential for further disruptions to oil flows.
