Iran says seven tankers were hit in the Strait of Hormuz overnight and warns the US of a wider response

Seven tankers were struck in the Strait of Hormuz overnight in what, if confirmed, would stand as the single worst day for shipping in the waterway since hostilities began on February 28 with joint US strikes on Iran. Iranian state TV, citing the Revolutionary Guard's navy, reported that four tankers were set on fire during oil transfers, while three others were disabled after striking naval mines. No party was named as responsible in the statement.

Tehran cautioned that any US effort to escort tankers through 'illegal passages' would broaden its response.

Since the war began, the Revolutionary Guard has made repeated strikes against US bases across Gulf countries.

The report provided no information on casualties or the nationalities of the stricken vessels.
