WARSAW, Poland (AP) — Polish prosecutors have charged a Ukrainian man with sabotage and diversionary activities on behalf of Russian intelligence, alleging he was paid to desecrate memorials honoring Polish victims of Ukrainian massacres in World War II in an effort to inflame tensions between the two countries.

Warsaw has long accused Russia of conducting hybrid operations aimed at driving a wedge between Poland and Ukraine. Poland has been one of Kyiv’s strongest supporters since Russia launched its full-scale invasion in 2022, but anti-Ukrainian sentiment has been growing in the country.
