Border guards have detained a woman suspected of helping wage a Russian "information war" against Poland and who has a ban on entering the country, according to a report.
The woman, who is a citizen of Russia and Cyprus, is to be expelled from Poland, public broadcaster Polish Radio's IAR news agency reported on Friday, Radio Poland reported.
The woman, named only as "Anastazja Z", worked to consolidate pro-Russian groups in Poland in order to challenge Polish government policy on historical issues and "replace it with a Russian narrative," according to IAR.
Polish security services said on Thursday they had detained a Russian citizen named as "Yekaterina C" and banned four people from entering the country after cracking down on a network waging a "hybrid and information war" masterminded by Moscow.
A security services spokesman warned that Russia was trying to destabilize Polish society and politics.
