Iran has imposed restrictions on ships using the strait, first in retaliation for the US-Israeli bombardment of the ​country, and then in response to a US blockade of Iranian ports.

​A Liberia-flagged container ship sustained damage to its bridge after ⁠being hit by gunfire and rocket-propelled grenades northeast of Oman.

The UKMTO ​said the master of the vessel reported being approached by an IRGC ​gunboat.

The vessel, it said, was subsequently fired upon. All crew members were safe and there was no fire or environmental impact due to the incident.

Maritime security ​sources said that three people were onboard that gunboat.

The master of the Greek-operated container ​ship also reported that no radio contact was made prior to the incident and ‌that ⁠the vessel had been initially informed that it had permission to transit the Strait of Hormuz.

The UKMTO later said that a second container vessel had been fired upon about eight nautical miles west of Iran. ​

The Panama-flagged vessel was not damaged ​and its ⁠crew members are safe.

Maritime security sources said that a third container ship was fired upon about eight ​nautical miles west of Iran while transiting outbound of ​the Strait ⁠of Hormuz.

The Liberia-flagged vessel, which was not damaged had stopped in the water. Its crew are safe, the sources said.

Before the war began on ⁠February 28, ​the waterway typically handled roughly one-fifth of ​the world’s oil and liquefied natural gas supply.
