A few days before the vote, the Bulgarian authorities were placed at the center of a series of incidents: the vessel CHELSEA 3 (flying the Maltese flag and owned by Ukrainians) was hit by three drones east of Bulgaria’s coastline, while a second vessel, HS Dignity, sank near Krapets. Prime Minister Rumen Radev stated that two vessels had been hit and one had sunk, and he subsequently met with Russia’s ambassador, Eleonora Mitrofanova, while Bulgaria announced that it would investigate the attacks with its allies and initiate consultations with Romania and Turkey on the safety of navigation. The European Commission condemned the attacks, describing them as “a new front of escalation”.
At the same time, Radev promoted a political line favorable to dialogue with Moscow: he supported the Trump–Putin agreement on diesel fuel supplies and criticized Ukrainian attacks on Russian refineries, stating that he did not support strikes against energy infrastructure “regardless of which side is targeted”. His government also received praise from Moscow for a more “restrained” rhetoric toward Russia, while Bulgaria announced that it would not join the “Coalition of the Willing”.
