The Polish government arrested nine people from a Russian spy ring in connection to alleged sabotage plots, Prime Minister Donald Tusk told Polish media outlet TVN24.
"We currently have nine suspects detained and indicted, who have been directly implicated in the name of Russian (intelligence) services in acts of sabotage in Poland," Tusk said.
The individuals were Polish, Ukrainian, and Belarusian citizens. Tusk also suggested they may have been recruited from criminal circles.
Acts of alleged sabotage include "beatings, arson, and attempted arson," not just in Poland but also in Latvia, Lithuania, and possibly even Sweden. Tusk explained that the group planned, for example, to set fire to a paint factory in Wroclaw, western Poland, and an Ikea center in Lithuania.
Earlier this year, a joint operation by Ukrainian and Polish law enforcement agencies led to the detention of a Polish citizen who allegedly offered to Russia to assassinate President Volodymyr Zelensky.
On his own initiative, the suspect meant to spy on the security of the Rzeszow airport in Poland, with the intention of helping Russian intelligence services plan a potential assassination of Zelensky during the latter's visit to Poland.
The Polish authorities detained the suspect and charged him with working for foreign intelligence services. The investigation is ongoing.
Several other suspects have been arrested in recent months in Germany, Austria, and Estonia for allegedly spying for Russia or other forms of collaboration with Russian intelligence.
