A group of foreign nationals have been arrested in Poland, suspected of spying on behalf of Russia. Their nationalities are not known.
The six people are said to have installed surveillance cameras in order to film transport routes used to deliver aid and material to war-torn Ukraine, according to the BBC.
“The whole network has been blown up. It was about a spy group, a group of people who gathered information for those attacking Ukraine,” said Polish Defense Minister Mariusz Blaszczak to the PR1 radio channel.
