Between 5–23 October, eight commercial vessels were struck or involved in incidents associated with drone attacks in the exclusive economic zones of Romania and Bulgaria, while Bulgarian rescue teams intervened in severe weather conditions. In parallel, Prime Minister Rumen Radev reported that he had summoned the Russian ambassador and conveyed Bulgaria’s position, insisting that the accusations must be supported by “clear evidence”.
In response, Bucharest’s CSAT decided to accelerate the development of surveillance capabilities and described the attacks as direct effects of Russian aggression, extending beyond Ukraine, while in Sofia Bulgaria announced investigations and consultations with Romania and Turkey to increase navigation safety.
