Polish-Ukrainian Relations Under Strain Amid Rising Tensions and Monastery Attack

A Ukrainian national fatally stabbed a priest and wounded four others at a Benedictine monastery in Jarosław, Poland, in September 2026. The attack occurred amid rising hostility toward Ukrainians in Poland, documented increases in hate incidents, shifting public opinion on Ukrainian refugees, and ongoing disputes over the historical legacy of the 1943–1945 Volhynia massacres. Polish public support for Ukrainian residency benefits has declined, and diplomatic relations between Warsaw and Kyiv have been strained by disputes over military unit naming conventions linked to the Ukrainian Insurgent Army.
