A knife attack at a Benedictine abbey in southeastern Poland has intensified anti-Ukrainian sentiment amid already strained relations between the two neighboring countries. On Thursday morning, a 31-year-old Ukrainian citizen identified as Ihor M.—whose full surname has not been disclosed under Polish privacy laws—entered the abbey in Jaroslaw and stabbed five individuals, including three clergymen and two laypersons. One of the priests later died in hospital. The suspect has been charged with murder and attempted murder.

Ukrainians constitute the largest immigrant group in Poland, with estimates placing their number at around 1.5 million. This population includes both refugees fleeing the ongoing conflict following Russia’s full-scale invasion of Ukraine in 2022 and longer-term economic migrants. Poland initially welcomed Ukrainian refugees with broad political and public support, granting them protected status soon after the invasion began. However, over subsequent years, public opinion shifted, and support for the continued acceptance of Ukrainian migrants has diminished amid growing political tensions between Warsaw and Kyiv and harsh rhetoric in both domestic and diplomatic arenas.

The attack occurred in Jaroslaw, a town situated merely 30 kilometers from the Ukrainian border, a region that has faced psychological strain due to its proximity to ongoing military operations in western Ukraine. Air raid alarms triggered by attacks across the border have heightened tensions for local residents, according to sociologist Marcin Piotrowski, who noted the area’s role as a strategic rear base for the conflict has made daily life difficult.

A study conducted in July by Poland’s Centre for Public Opinion Research (CBOS) revealed that for the first time since Russia’s 2014 annexation of Crimea, a majority of Poles (52 percent) opposed admitting Ukrainian refugees. The deteriorating climate is manifesting in increased social friction, with Ukrainians reporting more frequent unpleasant encounters, including discriminatory remarks and conflicts in public settings, as noted by Oleksandr Pestrykov, an advocacy expert with the Ukrainian House foundation in Warsaw.

Local residents of Jaroslaw reported a sharp rise in online hostility and misinformation following the attack. Adam Leszczynski, an associate professor at the Institute for Political Studies of the Polish Academy of Sciences, warned that the incident could be exploited by those opposed to strong Polish-Ukrainian ties, potentially leading to a surge in attacks against Ukrainians, an amplification of hate speech on social media, and increased support for far-right political groups.

The attack and its aftermath highlight the challenges faced by both communities in balancing humanitarian commitments with domestic concerns amid a complex and ongoing regional conflict.
