EU prepares sanctions after Russia’s drone hit a NATO building

Romania summoned Russia’s ambassador, convened its highest national security body, and received a personal condemnation from the President of the European Commission on Friday morning, turning a drone strike on a Galați apartment building into the most significant diplomatic confrontation between Bucharest and Moscow since Russia’s full-scale invasion of Ukraine began.

Romanian Foreign Minister Oana-Silvia Toiu confirmed she summoned Russia’s ambassador to the Ministry of Foreign Affairs headquarters following the Ministry of National Defense’s confirmation that the drone that struck a residential building in Galați overnight was of Russian origin. Her statement was direct and escalatory in its framing.

“Romania’s security is our absolute priority,” Toiu said. “We will officially communicate to him the effects that this lack of responsibility on the part of the Russian Federation will have on the diplomatic relations between our countries and the next steps at the European level regarding packages of sanctions.”

Romanian President Nicuşor Dan convened the Supreme Council of National Defense, the country’s highest security body, the same morning, a step reserved for situations that require immediate top-level governmental response.

European Commission President Ursula von der Leyen amplified the reaction at the EU level within hours. “Russia’s war of aggression has crossed yet another line,” she posted. “A Russian drone incursion struck a densely populated area in Romania, injuring civilians. On EU territory. We stand in full solidarity with Romania and its people. As we continue strengthening our security and deterrence, especially on our Eastern border, we will keep increasing the pressure on Russia. We are preparing a 21st package of sanctions.” Von der Leyen’s explicit linkage of the Galați strike to the upcoming sanctions package represents a direct escalation of the EU’s stated response, converting a military incident into a formal trigger for economic action against Russia.

Romania has documented 28 Russian drone incursions into its airspace since Moscow began targeting Ukrainian Danube port infrastructure, the export corridor through which Ukraine ships grain and cargo to international markets via the Black Sea. The previous 27 incidents produced summons, condemnations, and no material change in Russian behavior. Each prior diplomatic note delivered to the Russian ambassador stated that Romania expected Moscow to take all necessary measures to prevent future violations, and each time Moscow took none. The May 29 incident differs from its predecessors because, for the first time, a Russian drone produced confirmed civilian casualties on NATO and EU territory, a woman with first-degree burns and a 14-year-old suffering acute stress reaction, both hospitalized after a 10th-floor apartment caught fire.

Romania’s foreign minister has not been ambiguous about how Bucharest reads the cumulative pattern. Toiu told Euronews earlier, before the Galați strike, that many prior drone incursions from Russia were “designed to be deadly,” adding that “in two instances they were drones carrying explosives.” She also said Romania is coordinating with Baltic states and other Eastern flank allies on a unified approach to ambassador summons, framing the response not as a bilateral Romanian protest but as part of a coordinated alliance signal to Moscow: “This is a limit that should not be crossed either in the Baltics, in Romania, or anywhere else.”

The Supreme Council of National Defense summons adds institutional weight to what would otherwise be a standard diplomatic protest. The council, chaired by the Romanian president and including the prime minister, defense and foreign ministers, and intelligence chiefs, has authority over national security strategy and crisis response. Its convening signals that Romania is treating the Galați incident not as a routine airspace violation requiring a diplomatic note but as a matter requiring policy decisions at the highest level, including potentially a review of Romania’s rules of engagement for drone intercept.

Romania’s parliament passed Law No. 73 of 2025, establishing a legal framework that permits engagement of uninvited drones in peacetime when lives or property are at risk. Romanian forces scrambled two F-16 fighters and a military helicopter on the night of the Galați strike, with pilots authorized to engage. The drone was not intercepted before impact. The gap between the legal authority to act and the operational outcome of not acting before the drone reached a civilian building is precisely the kind of question that a Supreme Council meeting is convened to address.

NATO’s response followed its now established pattern: condemnation, statement of solidarity, and commitment to strengthen defenses. Secretary General Mark Rutte confirmed he was in contact with Romanian authorities and said through the NATO press office that the alliance condemns “Russia’s recklessness” and will continue strengthening defenses against drone threats. The alliance has not characterized any of the 28 Romanian airspace violations as an armed attack warranting a collective defense response under Article 5, the treaty provision that would obligate all NATO members to treat an attack on one as an attack on all. That assessment has remained consistent across every prior incident, and nothing in Friday’s response signals a change in the Article 5 calculus.

The 21st sanctions package that von der Leyen referenced was already in preparation before the Galați strike, announced on May 26 following drone incursions into Baltic EU member states’ airspace. Its acceleration in the wake of the first confirmed Russian drone casualties on EU soil adds both political urgency and substantive grounds to a package that Brussels was building anyway. Twenty prior sanctions packages have progressively tightened restrictions on Russian energy exports, financial transactions, and technology imports, with each package targeting remaining evasion pathways that allow sanctioned goods and capital to reach Moscow through third-country intermediaries.

Summoning an ambassador is among the most formal diplomatic signals a country can send short of expelling one. Romania has now done it repeatedly. Von der Leyen has now tied the next sanctions escalation directly to a drone strike on a NATO apartment building. The Supreme Council has convened. Every institutional instrument available below the threshold of military response has been activated. Whether that response changes Russia’s operational behavior in the skies above the Danube is a question that 27 prior incidents, each followed by similar institutional responses, already provide an answer to.
