The sirens' shrill alerts blare first; only subsequently do the blasts arrive.

For 48-year-old Robert Marian, a resident of Isaccea — a diminutive Romanian border town in eastern Tulcea County, situated along the Danube River at a crossing into Ukraine — the proximity of Russian drone strikes, merely hundreds of meters across the river, has become a wellspring of unremitting fear.

"There were alerts warning us that something was imminent," he said.

"It occurred a fortnight ago, perhaps three weeks.

I was asleep at midnight … One was more subdued, whereas another was exceedingly loud.

I became frightened and fled the house."

As Russia’s war in Ukraine grinds inexorably on, drone incursions into Romanian airspace have proliferated markedly.

The detonations just across the Danube serve as a stark reminder of the war’s proximity to NATO territory — at a juncture when many fear Russian President Vladimir Putin may seek to test the alliance’s resolve.

A Ukrainian border crossing with Romania was “deliberately damaged... as well as export infrastructure,” Ukrainian President Volodymyr Zelenskyy stated on Sept. 1.

Romanian customs announced the same day that activity at the Isaccea-Orlivka crossing had been temporarily suspended.

Alina Mihail, another denizen of Isaccea, avers that the drone alerts and blasts resounding across the border engender in her a feeling of sickness.

"I now endure countless a night wherein I no longer sleep," she said.

"I exist in a state of terror, my husband and I."

Data from Romania’s Ministry of National Defense indicate a threefold increase in drone incursions so far this year compared with the whole of 2025 — 27 compared with 9 — and more than double the number of drones and drone debris found on the NATO member’s territory, at 37 compared with 16.

Already within the current year, 73 attacks have been perpetrated near the border on Ukrainian territory, and some 56 military aircraft have been scrambled to “monitor and manage the situation.”

The preceding year bore witness to 28 attacks near the border, with 21 aircraft raised.

During the inaugural year of the war, but a solitary attack near the border was recorded.

In May, a drone, having crashed into an apartment block in the eastern town of Galati along the Danube River, injured a mother and child.

A drone that had entered Romania from neighboring Moldova was tracked through several counties last week before it reentered Moldova and crashed in a sunflower field.

Moscow has categorically repudiated allegations that it dispatched combat drones into Romanian airspace.

The escalating spectre of drones violating Romanian airspace—many of which officials have attributed to Russia—impelled the NATO member state to down four such unmanned aerial vehicles this year, marking the first instance of such action since the outbreak of the war in its immediate vicinity.

NATO member states throughout Europe have levelled accusations at Moscow, alleging its complicity in a succession of “hybrid war” operations directed against their nations — among them drone incursions, acts of sabotage, an attempted assault on a German airport, and a Danish helicopter subjected to flare fire over the Baltic Sea.

On Sept. 2, NATO Secretary-General Mark Rutte asserted that “Russia has grown increasingly reckless” as Moscow persists in prosecuting its ongoing war.

"We have witnessed an escalating incursion of drones and missiles into our airspace, along our eastern flank, engendering heightened risk," he said.

"The perils that Russia poses are unequivocal."

The preceding week had witnessed Polish Prime Minister Donald Tusk likewise issuing a caution that he had been apprised by CIA Director Jim Ratcliffe of intelligence indicating that Europe ought to brace itself for an escalation of Russian provocations, not least along the European Union's eastern flank.

Romanian Defense Minister Radu Miruta asserted that Russia is regarded as a “primary, significant threat” to the eastern flank and to Romania alike, both within the National Defense Strategy and in NATO assessments.

"We are engaged in deliberations concerning the requisite capabilities to counter this shared threat — confronting the selfsame risks as Poland and the Baltic states — and we are coordinating to ensure that these capabilities are apportioned in a manner conducive to interconnection," he said.

In the wake of Russia’s full-scale invasion of Ukraine in 2022, NATO, in a concerted effort to fortify its posture along Europe’s eastern flank, augmented its presence by dispatching additional multinational battle groups to Romania, Hungary, Bulgaria and Slovakia.

Yet in the preceding year, the United States curtailed its troop deployments to Eastern Europe—Romania among them—following a recalibration of Washington's military posture, a move officials insisted did not betoken any diminution of its commitment to NATO.

Miruta stated that upwards of 1,000 U.S. troops are stationed in Romania, a figure he characterized as exceeding that recorded following last year's U.S. troop rotation.

"We have a solid relationship," he said.

"The security dynamics along the eastern flank are highly fluid."

Miruta remarked that deliberations concerning NATO’s Article 5 — whereby an assault upon any member may elicit a collective riposte — “can take various directions,” yet affirmed that Romania presently possesses no intelligence intimating that a ground invasion is either imminent or probable.

"From this vantage point, we may rest assured," he remarked.

He further observed that the persistent menace confronting Romania is singular in nature, owing to Russia's recurrent assaults on Ukraine's Danube River ports, situated but a short distance beyond the natural riverine border.

"Once the border has been traversed, the intervening distance amounts to merely tens of meters, affording precious little time for reaction," he said.

"By contrast, in the Nordic countries, targets lie tens of kilometers distant, thereby furnishing a sufficiently comfortable window for interventions of various forms."

Cross-border live fire, at once visible and audible in certain areas, has for a considerable time kept Romanian residents on edge.

"We observe the drones approaching, we observe them making for those ports," Miruta appended.

"The majority halt there, bombarding port infrastructure, yet we cannot ascertain whether any might cross over to the other side … Should one indeed cross over, our communities … would find themselves imperilled."

Confronted with an ever-expanding spectrum of security threats, Romania and Poland procured the MEROPS system, which discharges short-range counter-drones to neutralize incoming stray drones.

The defense ministry likewise disclosed last month that it had received its inaugural 2.5 billion euros from the EU’s Security Action for Europe program, out of the total 16.6 billion allocated.

In June, the defense ministry likewise disclosed that it had concluded a $2 billion contract with an Israeli firm for the procurement of short- and very-short-range air defense systems, “designed to protect against aerial threats, including drones and cruise missiles.”

At the Ankara summit, Romanian President Nicusor Dan declared that defense expenditure would attain as much as 3.7% of GDP this year.

He further noted that Romania had acceded to NATO’s Drone Edge project, an initiative that seeks to channel upwards of $40 billion into “counter-drone capabilities” over the ensuing five years.

Back in Isaccea, Mihail recounts that she and her husband remain within the house whenever text alerts apprise them of potential airspace incursions.

"We are utterly bereft of support, with not a soul to come to our aid," she said.
