Four Cargo Ships Sunk Near Bulgaria as Russia Tests European Waters

Ukraine accuses Russia of sinking four cargo ships in the Black Sea this month.

The attacks occurred just outside the territorial waters of Bulgaria, a member of both the European Union and NATO. Ukrainian officials say aerial and surface drones were used in two separate operations. Moscow has not officially confirmed the strikes, but the location signals a direct challenge to the safety of Ukrainian grain exports through NATO waters.

The maritime incidents are part of a wider pattern of activity reported across Europe. European officials state that Russian fighter jets have briefly entered the airspace of Poland, Lithuania, and Estonia. Suspected Russian drones were shot down over Poland, Finland, and the Baltic states. In a separate incident, Ieva Cesniece, Latvia’s ambassador to Greece, described masked individuals on the Belarusian side of the border pushing migrants into Latvia. She said these groups threatened border guards and damaged surveillance equipment. Cesniece linked these actions to the war in Ukraine, noting that Russia tests NATO resilience as it struggles on the front lines.

Experts suggest Europe has been slow to respond to this hybrid warfare. Olena Tregub, head of Ukraine’s Independent Anti-Corruption Commission, said deterrence requires making operations costly for Moscow. She believes European governments have not done enough to track the money behind these networks. Oleksandr Danylyuk, a defense expert, argued that Russia is limited only by its current capabilities because it faces little retaliation. He stated that Ukrainians know about a war in Europe, not just a war in Ukraine.

Warnings have grown louder in recent months. Czech spy chief Michal Koudelka said in September that a Russian military attack on a NATO member could happen within months. Russian Foreign Ministry spokesperson Maria Zakharova declared European defense industries legitimate targets. Reports from EU intelligence agencies indicated Russia was targeting defense supply chains and planning to claim lives on European soil. German media reported incendiary devices were planted in the offices of defense firms in Munich.

Ukrainian President Volodymyr Zelenskyy addressed the European Council on October 16. He said the war will cost 155 billion euros next year and that Europe needs to provide an additional 70 billion euros. He asked for more funds to triple drone production. Zelenskyy noted that Europe has been slow to view sabotage and cyberattacks as early stages of a multidimensional war. Minna Alander of the Center for European Policy Analysis listed realistic retaliations, including visa denials and further sanctions on the Russian oil fleet.

Ukraine has developed its own weapons since 2023 and struck oil installations deep inside Russia. The country is now asking Europe, its main financial backer, to increase support. Zelenskyy said that with more resources, Ukraine could apply significantly more pressure on Russian forces. The European Council has not yet announced a specific new funding package for the coming year.
