There was ​no independent confirmation of the reports.

IRNA reported that ⁠the vessels had switched off their positioning and radar systems ​and attempted to use an unauthorised route through the strategic ​waterway. The second vessel was left immobilised after striking a mine, it added.

State media earlier reported that the other tanker had ​also struck a mine while attempting to transit the ​strait via a route not authorised by Iran.

The incidents come amid ‌heightened ⁠tensions around the strait, a key oil shipping route. Disruptions to shipping in the waterway due to the US-Israeli war on Iran have boosted global energy prices ​and inflation.

Maritime officials ​said on ⁠Wednesday that a container ship and a dry bulk carrier sank near the strait after ​being hit by projectiles in separate incidents.

Attacks ​around the ⁠waterway have surged over the past two weeks, with Iran saying it is stepping up strikes in response to ⁠the ​US blockade of its ports ​and tougher sanctions imposed last month.
