A cargo vessel reported coming under attack in the Red Sea on Sunday, according to the UK Maritime Trade Operations (UKMTO).
The British agency confirmed the distress signal and advised all vessels to transit with caution and report any suspicious activity.
The incident marks a geographic expansion of maritime threats, following a separate attack on a cargo ship in the Strait of Hormuz earlier this week.
That vessel was struck by an unidentified projectile near the coast of Oman on Thursday, also confirmed by UKMTO.
Repeated attacks on commercial shipping in key chokepoints are raising concerns about supply chain disruptions and insurance costs.
Traders are monitoring the situation for potential impacts on freight rates and energy logistics, particularly as tensions persist in the region.
