Two Tankers Hit Naval Mines in the Strait of Hormuz: Mines, Chokepoints and the Law of the Sea
Iran's Islamic Revolutionary Guard Corps (IRGC) said on 8 November 2026 that two oil tankers caught fire in the Strait of Hormuz after striking naval mines (explosive devices placed in the sea).
The IRGC said the tankers had used "unauthorised routes" and had switched off their navigation and positioning systems. It did not give their names or flags.
Since the war involving Iran began in late February 2026, Iran has tightly restricted traffic through the strait and insists that ships use routes it approves.
In response, the United States has imposed a naval blockade on Iranian ports and has escorted tankers through the strait. US Central Command (CENTCOM) has said it helped Gulf countries export about 1.5 billion barrels of oil through Hormuz since the summer, and that mines had been cleared from the waterway.
Iranian media also reported explosion sounds in Qeshm, Sirik, Jask and Bandar Abbas, coastal areas along the strait, and an "impact" at Jask.
The strait normally carries about one-fifth of the world's oil consumption, so any danger to shipping here affects fuel prices and supply worldwide, including in India.
Strait of Hormuz: Geography and Strategic Significance
The Strait of Hormuz is a narrow sea passage between Iran to the north and Oman (its Musandam peninsula) to the south. It links the Persian Gulf with the Gulf of Oman, which opens into the Arabian Sea. It is the only sea route out of the Gulf for most of the oil and gas of Saudi Arabia, Iraq, Kuwait, Qatar, the UAE and Iran, which is why it is called the world's most important oil chokepoint.
The burning tankers show how mines can make a narrow chokepoint like Hormuz dangerous even without a full closure. Because ships must squeeze into a few narrow lanes, a small number of mines, or even the fear of them, can slow traffic and push up oil prices and insurance costs.
Freedom of Navigation and the Law of the Sea (UNCLOS)
Freedom of navigation is the principle that ships of every country can sail the world's oceans freely. The main legal rulebook for the sea is the United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982 and in force since 1994. It divides the sea into zones (territorial sea, contiguous zone, exclusive economic zone, high seas) and sets the rights of ships passing through each zone, including through narrow straits.
Iran's demand that ships use only "authorised" routes, and mines in the strait, run against the idea of unhindered transit passage that most countries see as the law for international straits. This is why other powers have escorted tankers and why the legal status of Hormuz is debated again.
Naval Mines: Types, History, and Strategic Logic
A naval mine (sea mine) is an explosive device placed in the water that blows up when a ship comes into contact with it or comes near it. Unlike a torpedo or a missile, a mine does not chase its target; it waits. Mines are cheap, easy to lay and very hard to find, so even a weak navy can use them to block a port or a narrow sea route. That is why they are called "the weapon that waits".
Iran says the two tankers struck naval mines while using routes it had not approved. The incident shows how mines let a coastal state control a narrow chokepoint, and how a mine-cleared lane can quickly become unsafe again, which keeps shipping, oil prices and naval escorts under pressure.
