Yemen's Houthis said on Monday they launched a missile towards the Liberia-flagged Israeli-owned tanker 'Scarlet Ray' ship near Saudi Arabia's Red Sea port city of Yanbu.
The United Kingdom Maritime Trade Operations (UKMTO) said on Sunday that it received a report of an incident 40 nautical miles southwest of Yanbu.
A vessel reported "a splash in close proximity from an unknown projectile and heard a loud bang," the United Kingdom Maritime Trade Operations (UKMTO) said, adding that the vessel's crew were all safe and it was continuing to its next voyage.
In a later update, Ambrey said it assessed the vessel to be "aligned with" the targets of Yemen's Iran-aligned Houthis' profile given that it was publicly Israeli-owned.
Neither firm identified the party responsible for the incident, but UKMTO said authorities were investigating.
A Liberian-flagged chemical tanker is undamaged and still under the command of its captain, the vessel's manager said.
"We are aware of security reports alleging that our managed vessel Scarlet Ray was the target of a suspected Houthi attack," Singapore-based Eastern Pacific Shipping said in a statement.
"We confirm that the vessel has not sustained any damage and continues to operate under the command of its master," adding that all crew members were safe and accounted for.
Yanbu is a port city located on Western Saudi Arabia's Red Sea coast.
Saudi Arabia launched military campaign in Yemen against Houthis
Saudi Arabia led a coalition that launched a military campaign in Yemen from early 2015 to support the Gulf-backed government against the Houthis, who had seized the capital Sanaa in 2014.
The coalition has in the past foiled attempted assaults using explosive-laden boats it says were launched by the Houthis.
This is a developing story.
