In Poland, a 63-year-old man was arrested after planting a World War II-era mortar shell on a railway track, leading to an emergency situation in the town of Chechovice-Dzedzice, Silesian Voivodeship.
According to RMF24, a railway worker discovered the shell and promptly alerted the authorities.
The police confirmed that the 20 mm Soviet mortar shell was potentially very dangerous and could have caused a serious traffic accident. The explosive was safely removed and disposed of by police pyrotechnicians.
The man responsible for placing the shell on the track was charged with creating a direct risk of a disaster in ground traffic and faces up to three years in prison if convicted.
This incident comes as Polish Prime Minister Donald Tusk reported the recent arrest of 12 individuals planning acts of sabotage in Poland on behalf of Russia, and suggested Russian special services might be involved in a recent fire at the "Maryvilska 44" shopping center in Warsaw.
