Two vessels managed by Greek shipping firm Dynacom Tankers came under attack from unidentified projectiles while sailing off the coast of Oman on Monday, the company said.

The attacks come amid heightened tensions between the United States and Iran, which have increasingly disrupted maritime security in the Strait of Hormuz.

The re-escalation in fighting between the US and Iran is again threatening commercial shipping through the Strait of Hormuz as Iranian forces target vessels and the US moves to enforce its blockade of the country’s ports.

One of the vessels, the Malta-flagged Panamax tanker Kavomaleas, was hit by two projectiles, sparking a fire in its engine room that forced evacuation.

“After deploying the shipboard fire suppression system, the master made the decision to evacuate the vessel,” it said in a statement.

All crew members were safely located by Oman authorities and transferred to shore, Dynacom said, adding that it was in close contact with all relevant regional authorities.

British maritime risk management group Vanguard said the incident occurred as the ⁠vessel transited about 8 nautical miles northwest of Oman’s ‌Kumzar.

Kavomaleas had been set to load ‌oil products in the Gulf this week, according ​to shipbroking fixtures and one trade ‌source.

The United Kingdom Maritime Trade Operations agency, which reported earlier that ‌the vessel was on fire, said no environmental impact was reported.

In a separate statement, Dynacom Tankers also reported that another vessel, the Liberian-flagged Acheloos, was struck by a projectile on the same day.

“All crew members are safe and all accounted for. The ‌vessel has proceeded to anchorage while assessments take place. There are no reports of pollution at this time,” ⁠it said.

Acheloos is ⁠a Very Large Crude Carrier capable of carrying 2 million barrels of oil.

Greek maritime security company Marisks said Acheloos and Kavomaleas were struck at approximately the same time and were both transiting via the US-facilitated southern Hormuz corridor.

On Monday, Iran’s Revolutionary Guards said two oil tankers “exploded” and were immobilized after attempting to take what it called an unsafe southern route through the Strait of Hormuz.

On Sunday, the Guards also pointed to two ships involved in an “accident” in the same area. It was unclear if the two incidents were related or whether they were connected to ​that attacks on the Dynacom ​vessels.

All crew members from both vessels were reported safe, and no environmental pollution has been detected so far. These incidents underscore the persistent risks to commercial shipping in the region, where waterways remain vulnerable to projectiles and other threats. The industry will likely continue monitoring the situation closely for any further escalation.
