Iran's Islamic Revolutionary Guard Corps announced Wednesday that four oil tankers were destroyed after striking naval mines in a prohibited shipping lane south of the Strait of Hormuz. The elite force stated the tankers remain ablaze and that two additional vessels were seized for violating restrictions.

The IRGC also claimed its forces downed a U.S.-made MQ-9 drone over the strait early Wednesday morning, marking the 56th such incident according to the group. The statement, carried by Iranian state media, warned that forces stand ready to deliver a "final blow" to Israel and the United States.

These actions come amid ongoing tensions following a U.S.-Israeli military campaign against Iran earlier this year and a subsequent ceasefire. Iran has maintained restrictions on the strait, insisting on the use of northern routes through its territorial waters rather than the southern lane monitored by Oman.

Maritime security reports indicate a pattern of such incidents in recent weeks, with the UK Maritime Trade Operations noting multiple strikes on vessels since early October. The developments threaten global oil transit through the critical chokepoint, which handles a significant portion of the world's seaborne crude shipments.

Qatari mediation efforts continue between Washington and Tehran over reopening the waterway, with Iran linking any resumption to an end to U.S. naval measures. The latest claims underscore Tehran's determination to control passage and deter what it describes as violating traffic.

Analysts note the potential for further escalation if international shipping attempts to bypass Iranian directives. The incidents highlight risks to energy markets already strained by regional instability.
