Poland detains 6 suspects working for Russian intelligence, Polish official says

Poland’s Internal Security Agency has detained six people suspected of working for Russian special services and supplying Russia with military-grade materials used to make ammunition and weapons systems. The arrests form part of a wider investigation into suspected espionage and sabotage, as European governments prepare for possible Russian hybrid attacks.

The group comprises five Polish nationals aged 25 to 52 and a 37-year-old Russian woman, according to special services coordinator Tomasz Siemoniak. Four are in pre-trial detention on espionage charges, while two face non-custodial preventive measures. Investigators searched 21 sites in three provinces between 21 October and 2 November; Siemoniak said nearly 100 people had been named as suspects in espionage and sabotage cases since 1 January 2024.
