Polish officers have detained a Ukrainian accused of trying to murder a figure from Ukraine's weapons sector on Moscow's orders, Reuters reported. Investigators say his homemade explosive failed to detonate, and he fled to Poland, where officers detained him. The case is the latest in a run of Russian-directed plots targeting people tied to Ukraine across Europe.

A car bomb that failed

The suspect, named only as Serhii P. under Polish privacy rules, allegedly went after a figure in Ukraine's weapons sector in Irpin, a town in Kyiv Oblast just northwest of the capital. The ABW, Poland's Internal Security Agency, said he planted an improvised explosive device under a car used by the potential victim. The device was meant to be set off remotely with a cellphone, but it "did not detonate due to a malfunction," the agency said.

The suspect, a 63-year-old Ukrainian, fled to Poland after the attempt collapsed and was arrested in Warsaw on 5 August 2026, the Ukrainian outlet NV says. Polish authorities announced the arrest on 20 August and said it kept him from using Poland as a hideout while he dodged investigators. Prosecutors charged him with trying to kill with a bomb and with holding explosives without a permit. The charges carry a floor of 15 years behind bars and a ceiling of life, they said.

The ABW framed the case as proof that Russian intelligence runs operations far beyond its own borders, using people who move between countries to do the work. For years, Kyiv and Western capitals have said Moscow enlists people — Ukrainians among them — to run sabotage and spying missions, a charge Russia keeps rejecting.

A pattern across Europe

The plot fits a wider Russian campaign. Weeks earlier, Warsaw detained a Russian man whom Moscow had allegedly recruited to murder a Ukrainian-American in the same city. 

Earlier this year, Ukrainian investigators recently exposed a coordinated scheme to kill a Russian dissident and Ukraine supporter in Lithuania, German prosecutors filed sabotage charges against a Ukrainian and a Latvian, and an earlier plot targeted the chief of German arms-maker Rheinmetall.

Poland and the Baltic States have been named prime targets for Russian sabotage over their backing for Kyiv.

Russia has built or expanded at least 10 drone bases along its borders with Ukraine and Belarus, creating launch capacity for newer jet-powered attack drones, the most powerful of which could reach Warsaw, The Telegraph reported on 16 August 2026.

The network expands Russia’s capacity for mass drone attacks on Ukraine, while some sites could later threaten NATO. The findings come as Russia is also expanding bases and other military infrastructure along NATO’s northern and Baltic borders. The Telegraph found no evidence that Moscow is planning such an attack.

Seven of the 10 sites were used during recent bombardments of Kyiv, tracking data cited by The Telegraph showed. Using leaked documents, satellite imagery, and DroneSec's analysis, the newspaper identified at least 59 launch rails—tracks that launch fixed-wing drones without runways.

Around 20 appeared long enough for Russia’s latest long-range models, while one base could reportedly store over 1,000 drones.

Leaked Ukrainian documents cited by The Telegraph say the jet-powered Geran-4 and Geran-5 can carry 90-kilogram warheads. However, Ukrainian military intelligence puts the Geran-4’s range at up to 450 kilometers, while the larger Geran-5 has a stated range of up to 1,000 kilometers — enough to reach Warsaw from several of the new sites.

DroneSec founder Mike Monnik said expanded launch capacity and harder-to-intercept technology together increase pressure on Ukrainian air defenses.

Russia builds military infrastructure along NATO’s northern flank

Russia is also expanding military infrastructure elsewhere along NATO’s borders. A Nordic-Baltic investigation identified new or expanded infrastructure from Norway to Kaliningrad, with potential capacity for up to 115,000 personnel.

Satellite imagery showed new barracks, ammunition warehouses, and expanded bases near NATO’s northern and Baltic members.

The Institute for the Study of War, a US-based think tank, assessed that the construction likely supports future Russian operations against NATO rather than an imminent attack. Most Russian combat power remains committed to Ukraine, it said.

Other drone hubs support rapid Russian attacks

Russia has already built comparable hubs for attacks on Ukraine. Satellite imagery analyzed by the open-source intelligence group Strategic Aviation of Russia showed 10 additional launchers under construction at Tsymbulova in Oryol Oblast, following the start of work on 22 April 2026.

At occupied Donetsk Airport, the group identified enlarged launch pads, roads to a Geran and Gerbera drone warehouse, and the apparent construction of another storage building.

Ukraine’s Security Service (SBU) said it struck Shahed storage and launch sites at Primorsko-Akhtarsk on 2 August 2025. Ukraine’s Unmanned Systems Forces commander Robert "Madyar" Brovdi reported hitting drone logistics, warhead-storage, and preparation facilities at Donetsk Airport on 30 December 2025.

On 14 August 2026, Polish broadcaster RMF FM identified American-Ukrainian rapper and video blogger Kyivstoner as the previously unnamed target of an alleged Russian-directed assassination plot in Warsaw. The case comes as European authorities investigate suspected Russian attacks and sabotage across the continent.

The alleged plot against Kyivstoner comes amid attacks on Kremlin critics abroad, including the fatal shooting of a Russian opposition artist in Poland in June.

Polish authorities disclosed the Kyivstoner's case on 13 August but withheld the target’s identity. RMF’s identification points to a possible motive, though it relies on unverified allegations from the FSB, Russia's domestic security agency that Kyivstoner of managed drone deliveries intended for attacks near Moscow.

Who is Kyivstoner?

Kyivstoner was born Albert Vasiliev and uses the name Slevin Dadyan on his US passport. He gained attention through humorous videos and the Ukrainian group Hryby before releasing solo tracks, including “Leto” (Summer) and “Zvuk” (Sound).

In a 2025 interview, Vasiliev voiced support for Ukrainians and opposition to Russian occupation, saying Russian ruler Vladimir Putin made him angry and that he wanted civilians and soldiers to stop dying.

In July 2026, Russia’s FSB accused Kyivstoner of overseeing logistics for a foiled drone attack on a defense enterprise near Moscow.

The agency alleged that 35 drones assembled in Kyiv were concealed in a shipment of ceramic tiles and smuggled into Russia through Slovakia, Poland, and Belarus. Russian authorities also added Vasiliev to a register of people they label as involved in extremist or terrorist activity.

Vasiliev responded on Instagram by mocking Russia's allegation, saying he had been relaxing and playing video games rather than organizing an attack.

Russian authorities also accuse him of cooperating with Ukrainian intelligence. He denies the accusations, and RMF offered no independent evidence to substantiate them.

Suspect detained before alleged attack

Prime Minister Donald Tusk said Polish services detained the Russian suspect on 7 August, stopping the alleged attack “at the last minute.” US services assisted the operation. A Polish court remanded the man in custody for three months.

The journalists described the Russian citizen as a native of Donbas in eastern Ukraine. Tusk said the target, who holds Ukrainian and US passports, was “inconvenient to the Putin regime.”

The prime minister called it the first Russian-ordered attempt of its kind against a US citizen in another NATO country.

Killings and disrupted plots across Europe

Throughout Europe, Russia has tried to hunt down and kill anti-Kremlin critics and supporters of Ukraine. In June, Russian opposition artist Robert Kuzovkov, known as Semyon Skrepetsky, was shot dead in eastern Poland. Hours earlier, he had reported threats from “Russian patriots.” Polish authorities detained two Belarusian nationals, but have not attributed the killing to Moscow.

US and German services also reportedly foiled a Russian plot against Rheinmetall CEO Armin Papperger in 2024. German intelligence later treated the surveillance of Bavarian drone manufacturer Donaustahl’s CEO as a suspected planned assassination.
