On a Friday morning in early 2024, a stray uncrewed maritime drone linked to the ongoing war in neighboring Ukraine exploded at Romania’s pivotal Black Sea port of Constanta, marking the third major security incident to strike the NATO member in less than a month and triggering widespread emergency precautions across the country’s eastern coastline. Romania’s Ministry of National Defense confirmed in an official statement that the drone self-detonated at approximately 10:30 a.m. local time, adding that the craft was not part of the Romanian military’s arsenal and had no connection to recent military drills conducted in the Black Sea region. In the immediate aftermath of the blast, Romanian intelligence services, coast guard units and defense personnel moved quickly to secure and cordon off the affected area, and a full evacuation of the site was completed without any reports of injuries or loss of life. This latest incident comes just one week after a Russian attack drone, launched as part of a massive air assault on Ukrainian infrastructure, veered off course and slammed into an apartment building in Galati, a Danube port city in eastern Romania, leaving two people injured. As a NATO member with a direct border with war-torn Ukraine, Romania has faced a growing stream of stray military ordnance and drone incursions linked to the full-scale Russian invasion launched in February 2022, with incidents involving both Russian and Ukrainian uncrewed vessels and aircraft documented in recent months. Just two days prior to the Constanta explosion, Romanian military assets destroyed a separate stray maritime drone in international waters of the Black Sea. Since the outbreak of the war, the Romanian navy has successfully neutralized nine of the 156 drifting sea mines that have drifted into the Black Sea basin adjacent to Romanian territory, according to defense ministry data. In the wake of Friday’s detonation, emergency officials moved rapidly to secure broader coastal areas. Raed Arafat, head of Romania’s Department for Emergency Situations, told reporters that military helicopters were deployed to conduct sweeping searches for additional stray drones, and national emergency alert text messages were sent directly to residents across the affected region. “There is a possibility that there may be other drones,” Arafat told reporters, emphasizing that the sweeping measures were proactive rather than reactive. “We are not panicking. These are preventive measures. If there are other drones, we want to make sure there is not another explosion in an area where people are not evacuated.” By the end of the day, authorities confirmed that more than 1,300 people had been evacuated from multiple popular Black Sea beach resorts, and all main access routes leading to the coastal areas were temporarily blocked to keep civilians out of harm’s way. Romanian President Nicusor Dan praised the rapid, proactive response from law enforcement and national security agencies, noting that officials had acted before the detonation to mitigate risk. “With a military conflict on the border, it is obvious that the security environment we are in is a sensitive one, which is why we will maintain a high level of vigilance,” Dan said, adding that Friday’s incident was an unavoidable “direct consequence of the war of aggression unleashed by Russia against Ukraine.” The president stressed that the government’s top priority remains protecting civilian lives and critical port infrastructure, which serves as a key logistical hub for Ukrainian grain exports amid the ongoing blockade of Ukrainian Black Sea ports. The international community quickly moved to express solidarity with Romania following the incident. French President Emmanuel Macron issued a public statement of support Friday, reaffirming France’s commitment to defending NATO member territory. “We will do whatever your authorities consider as a necessity in order to protect the sovereignty of the land and the air,” Macron said. “You can count on us.” European Council President António Costa also issued a formal statement of solidarity, noting that the European Union stands firmly behind Romania in the face of repeated security incursions. “The EU condemns the repeated violations of airspace of Member States and reaffirms its unwavering commitment to the security of all Member States,” Costa wrote in a social media post Friday. “This is the third significant security incident in Romania in recent weeks. These incidents are a direct consequence of Russia’s war of aggression against Ukraine.” The report was filed by Courtney McGrath from Leamington Spa, England, with additional contributions from Sam McNeil based in Brussels.
