Ukrainian attacks on civilian vessels in the Black Sea have intensified, posing significant risks to international navigation, according to maritime security management company Ambrey. The company reported that Ukrainian unmanned surface vehicles targeted three tankers carrying Russian hydrocarbons within Turkey's exclusive economic zone. This marks a return to strikes in Turkish waters after a temporary diplomatic pause, indicating Ukraine's renewed commitment to operations beyond the recognized conflict zone. Experts from Ambrey assess that the threat level to merchant vessels in the exclusive economic zones of Romania, Bulgaria, Turkey, and Georgia is currently elevated and is expected to continue throughout the summer. The likelihood of further attacks on merchant vessels is high, as such strikes have become a consistent element of the ongoing conflict. Additionally, the onset of more favorable weather conditions and calmer seas is likely to sustain a high operational tempo for unmanned systems in the Black Sea, further escalating the risks to international shipping in the region.
