Iran Says Seven Tankers Hit in a Single Night Near Hormuz, the Worst Toll Since the War Began

Seven oil tankers were damaged overnight into Thursday in and around the Strait of Hormuz, Iranian state television reported, citing the naval arm of the Islamic Revolutionary Guard Corps (IRGC). If the account holds up, it would be the largest number of vessels hit in the waterway on a single day since the US-Israeli war with Iran began on February 28.

According to the IRGC statement, four tankers were struck at the same time and caught fire while transferring oil in the northern Persian Gulf, an activity the Guard described as illegal. Three more vessels hit naval mines west of the strait and were left unable to move. Iran did not name the ships, say which flags they were sailing under, or give any information on casualties, and none of the claims had been independently verified by Thursday afternoon, India time.

A warning aimed at Washington

The statement also carried a threat. The IRGC navy said any American effort to escort or route tankers through what it called "illegal passages" in the strait could draw a wider response, including strikes on US military bases across the region. Iran has hit US facilities in Gulf states several times since the war began, so the warning is not an abstract one for host governments such as Qatar, Bahrain and the UAE.

The timing matters. The claim arrives a day after the US State Department ordered non-emergency government staff and their families out of Saudi Arabia, citing Houthi missile and drone attacks on civilian airports and other infrastructure. One such strike on King Fahd International Airport in Dammam killed one person and injured eight, according to Saudi aviation authorities. Washington has said that order covers Saudi Arabia alone, not the wider Gulf.

What the market heard

Oil traders treated the report as another sign that the Gulf's shipping lanes are becoming harder, not easier, to use. Brent crude futures rose $1.93, or about 1.8 per cent, to $110.75 a barrel by 0442 GMT, and later traded near $111.30. US benchmark West Texas Intermediate climbed to roughly $99.

Traffic through Hormuz was already a fraction of normal before this latest round. One independent ship-tracking service counted just four transits on October 18, against a pre-war average of about 85 a day. Every additional incident raises insurance premiums and freight rates for the few owners still willing to send ships through, which feeds directly into the delivered price of crude for importers.

Why it matters beyond the Gulf

Three points stand out from the IRGC's account.

The mines. Fires on tankers can be blamed on targeted strikes, but mines are indiscriminate. If three vessels were disabled by mines west of the strait, that suggests the hazard has spread beyond the narrowest stretch of water and into approaches that shipowners may have regarded as safer.

The framing of "illegal" transfers. By describing the four burning tankers as engaged in illegal ship-to-ship transfers, Tehran appears to be signalling which trade it considers a legitimate target. That gives shipowners and insurers little comfort, because the line between permitted and forbidden activity is being drawn by one side alone.

The escalation ladder. The explicit mention of US bases follows weeks of Houthi attacks deeper into Saudi Arabia and an attack on an LNG tanker off Yemen (see our earlier coverage). The conflict's maritime front is widening rather than narrowing.

For India, which relies on Gulf routes for a large share of its crude and LPG imports, the immediate channel is price. Brent holding above $110 keeps pressure on the rupee, on oil marketing companies' margins and on the government's fuel tax decisions. Diplomatic efforts, including a Qatar-Pakistan proposal floated earlier this week, have yet to produce a pause on the water.
