Russian forces struck port infrastructure and military-linked vessels in the Ukrainian cities of Nikolayev and Chernomorsk on Friday, according to the state-run TASS news agency.
The attacks targeted a bulk carrier delivering cargo for the Ukrainian armed forces and a CV-90 high-speed landing craft operated by the Ukrainian Navy.
The strikes underscore the persistent threat to maritime logistics in the Black Sea region.
While the immediate impact on global energy markets may be limited, any escalation in port damage or vessel losses can tighten regional freight capacity and increase insurance premiums for ships transiting the corridor.
Traders are monitoring whether the attacks will lead to broader disruptions in grain or energy exports from Ukraine.
This development follows a series of overnight strikes on three other Ukrainian ports, where Russian forces targeted loading facilities and fuel reserves, as previously reported by Asharq Al-Awsat and New Straits Time.
