Two vessels came under attack on Monday in the Red Sea off Yemen's port city of Hodeidah, with one ship reporting it had sustained some damage, Britain's maritime agency said, APA reports citing Reuters.
A vessel 97 nautical miles northwest of Hodeidah was attacked by an uncrewed surface vessel that hit its port side causing some damage and light smoke, the United Kingdom Maritime Trade Operations (UKMTO) said.
The ship and its crew were reported safe and proceeding to next port of call, UKMTO added.
Another merchant vessel, 70 nautical miles southwest of Hodeidah, reported three missiles had exploded nearby, after the ship earlier came under attack by three small craft, UKMTO and security firm Ambrey said separately.
The vessel reported one missile exploding at 0800 GMT, then another two missiles around 45 minutes later, according to UKMTO.
Earlier on Monday, an unmanned small craft collided with the vessel twice and two manned small craft fired at it, UKMTO said.
Both the vessel and crew were also reported as safe and proceeding to hte next port of call, Ambrey said.
