Two vessels sustained damage after being hit with suspected Houthi missiles and a sea drone off Yemen's Hodeidah port early on Tuesday, maritime security agencies and sources monitoring the area said.
Both vessels reported that their crews were safe.
One of the vessels, which sources said was a Panama-flagged tanker, reported being hit by an Uncrewed Surface Vessel (USV) 64 nautical miles northwest of Hodeidah, the United Kingdom Maritime Trade Operations agency said.
It was damaged on its port side ballast tank, British security firm Ambrey said, adding that it was proceeding to its port of call.
The vessel had earlier reported seeing four splashes on the water close to it, which a maritime security source said were attempted missile attacks.
The second vessel, which sources said was a Liberia-flagged bulker, sustained damage after it was hit by a missile about 97 nautical miles northwest of Hodeidah, Ambrey and maritime security sources said. The firm said it was bound for Suez.
Houthis have targeted more than 80 merchant vessels with missiles and drones since the war in Gaza started in October. They have seized one vessel and sank two in the campaign that has also killed four sailors. Other missiles and drones have either been intercepted by a US-led coalition in the Red Sea or failed to reach their targets, which have included Western military vessels.
The last attack on a merchant ship by the Houthis came on Sept. 2.
The Houthis also continue to launch missiles targeting Israel, drawing retaliatory airstrikes from the Israelis this weekend on Hodeidah.
