A tanker reported hearing an explosion in the southern Red Sea on Tuesday evening, according to the United Kingdom Maritime Trade Operations (UKMTO).
The maritime agency confirmed the report of suspicious activity but stated that the crew was safe and no injuries were reported.
The incident adds to a growing list of security concerns in one of the world's most critical energy transit corridors.
The report comes amid heightened volatility in shipping and energy markets.
Earlier this week, Iran's Revolutionary Guards struck three tankers in the Strait of Hormuz, reigniting fears of broader disruption to global oil flows.
The southern Red Sea incident, while isolated in terms of immediate damage, underscores the persistent threat to commercial vessels transiting the region.
