On the night of 9 September 2026, the silence on the Ukrainian Moldovan border was torn apart by the roar of several Russian Geran-type drones attacking the Starokozache international checkpoint in Odesa region. The raid killed two civilians and wounded three others. Border terminals were destroyed, and a passenger bus, trucks and passenger cars caught fire.
Just four days later the blow fell on Ukraine’s western frontier. Near the Yahodyn checkpoint on the Ukrainian Polish section, a drone struck the locomotive of the Kyiv–Warsaw passenger train. Fifteen minutes earlier, an international service had left Yahodyn station carrying a foreign delegation that included former British prime minister Boris Johnson, former CIA director David Petraeus and former Swedish prime minister Carl Bildt.
Since late August 2026, Russian drones have struck at least five Ukrainian border crossings with Moldova and with Romania, a NATO member. The raids on Starokozache and Yahodyn were another manifestation of a systematic campaign in which regular Russian attacks on Ukraine’s border infrastructure have risen to the level of strategic pressure on the country’s economy and on the security of the European Union.
The sequence of attacks shows a deliberate shift of Russian firepower onto land and river logistics. The Orlivka–Isaccea river ferry complex on the Danube, linking Ukraine with Romania, was hit in a series of attacks on 1 and 6 September 2026. Damage to the crossing infrastructure halted ferry traffic and blocked an alternative overland export route. On the Moldovan direction, UAV strikes on 21 and 25 August 2026 against the Tabaky and Vynohradivka–Vulcănești checkpoints inflicted serious damage on administrative and customs terminals and froze the processing of freight. Attacks have also continued against approaches to the Reni–Giurgiulești line and against transport infrastructure along the entire Danube corridor.
Russia’s ambassador-at-large Rodion Miroshnyk has stated openly that the strikes are supposedly aimed at logistics facilities through which, in Moscow’s telling, military aid is flowing. The Ukrainian side calls what is happening terrorism against civilian objects and an attempt to paralyse key supply and export routes.
After the blockade and regular shelling of the Black Sea ports of Greater Odesa, the land and Danube corridors became critical lifelines for Ukraine, since Western assistance, humanitarian cargoes, and grain and food exports all move through them. The crossings in Odesa region, far from the front line, turned into a key hub for shipments to Moldova, Romania and the port of Constanța. At the same time, they proved among the most vulnerable, because Russian drones are launched from the Black Sea. Flying at extremely low altitude, hugging the terrain along riverbeds and limans, they reduce radar detection range and create serious problems for mobile fire groups.
Systematic Russian strikes on western checkpoints are intended to economically strangle Ukraine by raising the cost and duration of logistics, to apply psychological pressure on the EU and NATO by demonstrating the ability to “reach” their borders, and to force Kyiv to divert scarce air-defence systems to cover a long state frontier.
Ukrainian air defence remains highly effective. On the night of 21 September 2026, it shot down or suppressed 148 of 172 incoming Russian UAVs. Border checkpoints, however, remain relatively “soft” targets. Dense stationary cover is concentrated around major cities, ports and energy facilities, while the border itself is held by mobile fire groups of the State Border Guard Service equipped with heavy machine guns, electronic-warfare systems and interceptor drones. Against massed Geran raids and their jet-powered variants these forces are often insufficient. As Border Guard Service spokesman Andriy Demchenko notes, the high speed of the jet drones sharply reduces reaction time. Because there are few or no properly equipped shelters, checkpoints facing a high threat must temporarily halt operations, switch off lighting and evacuate staff together with civilians.
The risk that the conflict will spill beyond Ukraine has forced neighbouring states to revise their security measures. Under pressure from repeated Russian air attacks, Moldova’s Border Police on 12 September 2026 decided to withdraw its border guards and customs officers from Ukrainian territory for 90 days, ending the previous joint-control arrangement. Operations in that format ceased at Giurgiulești–Reni, Briceni–Rososhany and Criva–Mamalyha. All checks were moved exclusively onto the Moldovan side, immediately producing kilometre-long queues. After further drone incursions, President Maia Sandu said Moldova was making emergency investments in air defence and would not yield to intimidation.
Romania, responding to violations of its airspace, scrambled Spanish Air Force F-18 fighters on 8 September as part of a NATO air-policing mission after a Russian drone flew deep into Romanian airspace before crashing. Bucharest is increasing defence spending and deploying specialised anti-drone systems along the Danube.
Strikes on border infrastructure are hitting Ukraine’s agricultural sector and the regional economy. Disruptions at the Danube ports of Izmail and Reni and at the Orlivka ferry force grain flows inland, producing queues, higher freight costs and falling farm-gate prices inside Ukraine.
A special place in this logistics escalation belongs to the Polish section of the border, the main overland hub for military and humanitarian aid to Ukraine. Events on 13 and 17 September 2026 around the largest international crossing, Yahodyn–Dorohusk, showed that the key arteries linking Kyiv with Warsaw had come under fire. A drone strike on the locomotive of the Kyiv–Warsaw passenger train only two kilometres from Polish territory, together with a series of powerful explosions at a filling station and freight terminals immediately next to the checkpoint, drew a harsh response from Poland. The Polish Armed Forces Operational Command repeatedly scrambled Polish and allied aircraft to intercept targets approaching the border. Interior Minister Marcin Kierwiński officially described the incidents as acts of direct Russian terrorism at NATO’s gates. In response to systematic incoming strikes in the border strip, Warsaw announced accelerated fortification of its eastern frontier and intensified consultations within the Alliance, treating the attacks on Yahodyn as an attempt by the Kremlin to paralyse Europe’s main transit corridor.
The main financial burden of repairing the damage falls on Ukraine’s budget. Tens of millions of hryvnias have already been spent in 2025–2026 on restoring checkpoint infrastructure, road surfaces and equipment. The European Investment Bank and EU TEN-T funds finance strategic modernisation of border crossings, but emergency reconstruction after strikes remains Ukraine’s task. Neighbouring countries also incur indirect costs, including redeploying personnel, reinforcing air defence and dealing with disruptions to air traffic.
The strikes on Starokozache, Orlivka and Yahodyn have shown that these are no longer isolated incidents. They have become an instrument by which the Kremlin is moving the war to the very borders of the EU and NATO, testing the Alliance’s willingness to respond to provocations and raising the price of supporting Kyiv for European states. The logistics of the war and Europe’s security policy are now bound into a single knot. Without a reinforced air-defence umbrella over Ukraine’s western borders, the region’s key transport arteries will remain at constant risk of paralysis.
