March 16 (UPI) -- Six foreign citizens have been charged in Poland for planning "sabotage actions," as part of a Russian spy ring, Polish Interior Minister Mariusz Kaminski said Thursday.
Agents of Poland's internal security agency, the ABW, discovered GPS trackers that were intended to be mounted on aid deliveries in the possession of the suspects, which Kaminski said they would use to monitor railway traffic and weapons shipments to Ukraine.
