Strait of Hormuz’s opening delayed as Iran struggles to locate own sea mines: Report

April 11, 2026

A fresh snag has emerged in the already tense geopolitical landscape. Reportedly, following the US-Iran ceasefire, now Tehran is facing difficulties in reopening the strategically crucial Strait of Hormuz because of sea mines that were laid during hostilities.

According to a report by The New York Times, which cited US officials, Tehran is unable to locate all the mines it deployed in the vital shipping corridor, the Strait of Hormuz. The recent complication has raised serious concerns over maritime safety and global oil supply.

Strait of Hormuz: Critical Oil Transit Route

The Strait of Hormuz, which links the Persian Gulf to the Gulf of Oman and the Arabian Sea, is one of the world’s most critical oil transit routes, carrying nearly a fifth of global oil shipments. For countries like India, the dependency on Hormuz is even higher, as a significant portion of its energy imports passes through this narrow channel.

Iran deployed mines, now unable to locate

As per the report, Iran had deployed mines using small boats last month, following the joint airstrikes by the US and Israel.

However, reportedly, the mining operation may not have been systematically documented. Now, as a result, some of the devices, even when recorded, were laid in a manner that allowed them to drift, making detection and removal significantly more challenging.

US calls it Haphazard

US officials described the mining effort as “haphazard,” the New York Times reported, highlighting the risks posed to commercial shipping.

The situation has become grimmer as its shadow also looms over ongoing diplomatic efforts, particularly the high-stakes talks between US and Iran which is currently underway in Islamabad.

Another passage is open for ships

“Iran’s Islamic Revolutionary Guard Corps had issued warnings that ships passing through the strait could collide with sea mines. It, however, left another passage open to allow the transit of ships that pay a toll,” said the report.

Adding to concerns, Iran’s Islamic Revolutionary Guard Corps (IRGC) has issued a public advisory warning vessels about the potential danger.

“All ships intending to transit the Strait of Hormuz are hereby notified that to comply with the principles of maritime safety and to be protected from possible collisions with sea mines… they should take alternative routes for traffic in the Strait of Hormuz,” the IRGC said in a statement.

While Iran has agreed to reopen the strait following a ceasefire with the US, just ahead of a deadline set by President Donald Trump, its inability to swiftly clear the mines laid by them has delayed full restoration of normal shipping operations.
