Iranian forces have prevented a tanker from transiting the Strait of Hormuz without coordination, Reuters reports, citing Iran’s state media.

Iranian media earlier reported sounds of explosions near Bandar Abbas, but state news agency IRNA later said no explosions had been reported in the port city and that any sounds could have been related to military activity in maritime areas.

Iranian media also reported explosion sounds off the coast of Sirik.

A military source told state media that the sounds heard near Sirik were linked to Iranian forces confronting an oil tanker attempting to pass through the Strait of Hormuz.

The tanker later complied with the ban on transit after receiving warnings from the IRGC Navy, the source said.
