The strategic waters of the Strait of Hormuz have erupted into new chaos after Iran’s powerful Islamic Revolutionary Guard Corps (IRGC) claimed responsibility for a dramatic drone strike against an oil tanker passing through the vital global shipping corridor.

According to Iranian military statements, the tanker — identified as Prima, a Malta-flagged oil and chemical carrier — was struck by an explosive drone after allegedly ignoring repeated warnings from the IRGC Navy about navigating the strait amid escalating hostilities.

Iranian officials said the vessel continued moving despite security alerts, prompting IRGC forces to launch the drone attack. The strike reportedly hit the tanker while it was transiting the narrow waterway linking the Persian Gulf to the Gulf of Oman, one of the most critical energy arteries in the world.

Global Oil Route Under Threat

The attack has rattled global shipping companies and energy markets because roughly 20% of the world’s oil supply passes through the Strait of Hormuz every day.

Following the incident, many commercial vessels reportedly slowed or halted their transit through the strait amid fears of further attacks. Insurance costs for ships operating in the region have surged, while energy traders warn that even brief disruptions could trigger major price spikes in global oil markets.
