An explosion struck an Israeli-owned cargo ship sailing through the Gulf of Oman on Friday, an incident renewing concerns about ship security amid escalating tensions between the US and Iran.

Investigations are ongoing. Vessel and crew are safe,” the United Kingdom Maritime Trade Operations (UKMTO) said. The UKMTO did not give details on the cause of the explosion.

Maritime security firm Dryad Global said the MV HELIOS RAY was a vehicle carrier owned by Helios Ray Ltd, an Israeli firm registered in the Isle of Man. The ship was en route to Singapore from Dammam in Saudi Arabia.
