A tanker was hit by an unidentified projectile 70 nautical miles southwest of Al Shuqaiq in Saudi Arabia, according to the UK Maritime Trade Operations (UKMTO).
The maritime security agency confirmed the incident but reported no casualties.
The attack adds to a growing list of disruptions in the region, following a separate incident earlier this week where an oil tanker was struck near the Strait of Hormuz.
The latest incident highlights the persistent security challenges facing commercial shipping in the Arabian Peninsula.
While the immediate impact on global oil supplies remains limited, the frequency of such events continues to weigh on market sentiment.
Traders are closely monitoring the situation for any signs of broader escalation that could disrupt the flow of crude and refined products from the Gulf.
