# Poland and Romania detain Ukrainians in suspected Russian sabotage plot
Authorities in Poland and Romania have detained Ukrainian citizens over an alleged Russian intelligence sabotage campaign involving explosive parcels and other acts intended to destabilize countries supporting Ukraine.
In Poland, prosecutors said a Ukrainian citizen was detained for allegedly working for Russian intelligence services. The person was said to be one of eight individuals held in recent days on suspicion of sabotage preparation across the country. Prime Minister Donald Tusk posted about the arrests on X, and Polish special services minister Tomasz Siemoniak said the work involved reconnaissance of military sites and critical infrastructure, preparation of sabotage materials and direct attacks.
Romanian authorities said separately that two Ukrainians, aged 21 and 24, acting on behalf of Russian intelligence, deposited two parcels containing improvised explosive devices at an international courier company in Bucharest. Specialists from Romanian intelligence defused the devices. The pair were placed under preventative arrest for 30 days.
According to Polish prosecutors, the broader plot included sending shipments containing explosives and incendiary materials to Ukraine so they would spontaneously combust or explode during transport. The stated aim, officials said, was to intimidate populations and destabilize European Union countries that support Kyiv.
The arrests fit a pattern seen since Russia's full-scale invasion of Ukraine in February 2022. Polish authorities say they have detained dozens of people over suspected sabotage and espionage, while Western officials have accused Russia and its proxies of carrying out dozens of attacks and other incidents across Europe over the past several years.
The packet also notes that in Lithuania last month prosecutors uncovered a Russia-linked network suspected of planning arson attacks in several European countries. That broader regional backdrop helps explain why authorities are treating the latest detentions as part of a transnational security problem rather than isolated criminal incidents.
The current record does not establish guilt in court. It shows allegations, arrests and defused devices. But it also shows how European security services are responding to a threat they believe is linked to Moscow's intelligence apparatus and intended to create fear as well as practical disruption.
For countries on NATO's eastern flank, the concern is not only about one parcel or one detainee. It is about the possibility that sabotage operations are being built through ordinary commercial systems, with courier services, storage points and routine cross-border movement used as cover.
That is why the detentions in Poland and Romania matter beyond their immediate legal consequences. They reflect a wider counterintelligence contest that has become one of the most persistent byproducts of the war in Ukraine.
