What happened overnight

During the night of 28–29 May, the Russian Federation resumed drone strikes on civilian and infrastructure targets in Ukraine near the river border with Romania. One of those drones penetrated Romanian airspace, was tracked by radar to the southern part of the city of Galati, and crashed onto the roof of a 10-storey block of flats, causing an explosion and a fire upon impact. The Romanian defence ministry stated that the entire payload of the Geran-2 drone, of Russian origin, detonated.

Casualties and immediate response

The two occupants of the affected apartment were able to evacuate the building on their own and received medical treatment on site for abrasions. Romanian emergency services confirmed that no other injuries were reported. Two F-16 fighters were scrambled from the Fetesti air base in eastern Romania and were authorised to engage targets for the duration of the alert, though the drone was not intercepted.

Bucharest's diplomatic reaction

Romania summoned the Russian ambassador and foreign minister Oana Toiu called the incident a "serious violation of international law." Bucharest requested measures to accelerate the transfer of anti-drone capabilities to Romania and informed NATO Secretary-General Mark Rutte of the situation. President Nicusor Dan asked the foreign ministry to prepare a package of measures against Moscow "proportionate to this very serious situation."

“We will officially communicate the consequences that this lack of responsibility on Russia's part will have on diplomatic relations between our two countries.”

NATO and EU allies condemn Moscow

NATO spokesperson condemned Russia's recklessness and said the alliance will continue to strengthen defences against all threats, including drones. Secretary-General Mark Rutte deplored Russia's "reckless behaviour," calling it "a danger to us all." European Commission President Ursula von der Leyen said Russia had "crossed yet another line," while EU foreign policy chief Kaja Kallas described the strike as "a flagrant and serious" violation of Romania's sovereignty and European airspace.

“This represents a dangerous and irresponsible escalation that cannot be tolerated. In the face of these threats, NATO's cohesion remains unshakable: the security of one member of the Alliance and the European Union is the security of all of us.”

Kyiv and the wider context

Ukraine's foreign minister Andriï Sybiga said the incident proved once again that Russian aggression constitutes a real threat to the Black Sea region and to all of Europe. Romania has experienced Russian drones breaching its airspace 28 times since Moscow began attacking Ukrainian ports across the Danube, but this is the first time a drone has struck a densely populated area and caused injuries on Romanian territory. The Russian defence ministry made no immediate comment.

What comes next

Romania has convened its Supreme Council of National Defence to assess the situation. While Article 4 of the North Atlantic Treaty allows any member to raise a security concern before the North Atlantic Council, and Article 5 provides for collective defence, Romanian authorities currently assess that the drone was heading toward Ukraine and crashed accidentally on Romanian territory. No military retaliation appears imminent, but the incident is likely to accelerate the deployment of additional anti-drone systems to NATO's eastern flank.
