An LPG tanker was struck by debris from unknown projectiles while transiting outbound from the Strait of Hormuz, the United Kingdom Maritime Trade Operations (UKMTO) said Monday.

The UKMTO said it received a delayed report of the incident from the vessel’s master. All crew members were reported safe, and no environmental impact was recorded, The Caspian Post reports.

The tanker will continue to its next port of call while authorities investigate the incident, according to the UKMTO.

It was the second tanker-related incident recorded by the UKMTO on Monday. Earlier in the day, the agency reported that another tanker transiting the Strait of Hormuz had been hit by an unknown projectile, leaving two crew members with minor injuries.

That vessel also continued to its next port under its own power.
