A total of 20 train lines in Poland had to come to a halt after the train signal frequency was disrupted. The signal channel was manipulated to play the national anthem of Russia and the speeches of Vladimir Putin, the President of Russia, causing an emergency stop signal to be sent as well. The affected trains were mainly in the city of Szczecin, and authorities are currently investigating who was behind this disruption.
Poland is a crucial point for the delivery of military equipment that Ukraine has received assistance from Western countries.
