Ukrainian citizen attacks Benedictine monastery in Poland, killing at least one priest

Why it matters

The attack by a Ukrainian citizen at a Catholic monastery near the Ukrainian border carries diplomatic weight well beyond the criminal incident itself. It drew responses from the presidents and prime ministers of both Poland and Ukraine, and Polish and Ukrainian officials alike warned it could fuel anti-Ukrainian sentiment in a country that has hosted large numbers of Ukrainian refugees since 2022. Polish suggestions that Russian involvement could not be ruled out, and a Polish mayor's characterization of the event as a probable terrorist attack, layered further political and security dimensions onto a case in which the attacker's motives remained officially unknown.

What happened

Around 09:30 local time on the morning of Thursday, 24 September, a man armed with a knife attacked people on the grounds of the Benedictine Sisters' Abbey on Benedyktyńska Street in Jarosław, a city in Poland's Subcarpathian (Podkarpackie) Voivodeship about 30 kilometres from the Ukrainian border. Police who were notified at that time arrived and detained the suspect at the scene. The attacker was identified as a 31-year-old Ukrainian citizen, Ihor M., who had entered Poland from Germany that same day and was heading toward the Korczowa border crossing with Ukraine but did not cross it. Investigators said the knife used in the attack was taken from the monastery's kitchen; prosecutors explicitly rejected early reports that the weapon was a machete.

Five people were injured — four men, including three priests, and one woman — and all were hospitalized, with three reported to be in very serious condition. At least one priest, Father Stanisław, died of his injuries. Later reporting citing the Rzeszów Cathedral said a second priest, Marek Pieńkowski, also died, bringing the death toll to two. Polish prosecutors said at the time of reporting that they had no information on the attacker's motives; a blood sample was taken to test for alcohol and drugs, and the suspect had not yet been formally interrogated.

Ukrainian President Volodymyr Zelensky called the incident a "horrible crime," expressed condolences to the family of the deceased and wished a speedy recovery to the injured, and said the perpetrator must bear full responsibility under the law. Polish Prime Minister Donald Tusk said the detained attacker would be punished with the full severity of Polish law. The Embassy of Ukraine in Poland condemned the attack, expressed condolences and thanked Polish law enforcement and medical services, calling for accountability to rest solely on the law. Ukraine's ambassador to Poland, Vasyl Bodnar, said the suspect resides permanently in Germany, had attempted to cross into Ukraine on 23 September but was turned back for lack of insurance, was in a psychiatric hospital and may have had mental health disorders, and that preliminary information indicated no national motive. Polish Interior Minister Marcin Kierwiński wrote on X that the suspect was immediately detained after attacking five people. Local authorities in Jarosław cancelled classes at neighbouring schools and declared a period of mourning until the end of the week.

How Ukrainian sources describe it

Ukrainian-language coverage led with official Ukrainian reactions — President Zelensky's condemnation and condolences, and the Embassy of Ukraine in Poland's statement — and prominently featured Ambassador Vasyl Bodnar's account that the suspect resides in Germany, had been turned back at the Ukrainian border the day before, and was in a psychiatric hospital with possible mental health disorders, with no national motive indicated. Ukrainian outlets consistently highlighted the suspect's entry from Germany on the day of the attack and his failed attempt to cross into Ukraine, framing the incident as the act of an individual rather than a community pattern. Several Ukrainian reports also cited Polish officials' own warnings about the risk of a spike in anti-Ukrainian hostility, leaning on Polish voices to caution against generalisations about Ukrainians in Poland.

How international sources describe it

English- and German-language reporting centred on the basic facts — the monastery location, timing, the attacker's profile, the victims and official Polish responses from Prime Minister Tusk, Interior Minister Kierwiński and Jarosław Mayor Marcin Nazarewicz — and gave comparatively less weight to Ukrainian diplomatic messaging. The German-language coverage drew attention to the attacker's transnational route, noting his entry from Germany and the proximity of Jarosław to the Ukrainian border, and led with the killing and Polish law-enforcement assurances, presenting the event primarily as a Polish security and criminal matter rather than a bilateral diplomatic incident.

Where reporting differs

Sources diverge on the death toll: most early reports describe one priest killed (Father Stanisław), while later reporting citing the Rzeszów Cathedral states two priests — Marek Pieńkowski and Stanisław Zbojnowicz — died. Reports also disagree on the weapon: some witnesses and one Polish outlet described a machete, but prosecutors explicitly rejected that account and said the attacker used a kitchen knife taken from the monastery. Witnesses claimed he specifically targeted priests, striking them repeatedly with a long knife, while prosecutors said at the time of reporting that this targeting had not been confirmed. On motive, Polish Deputy Interior Minister Wiesław Leśniakiewicz said Russian involvement could not be ruled out, whereas Ukrainian Ambassador Vasyl Bodnar said preliminary information indicated no national motive behind the attack.

Background

The Benedictine sisters' monastery in Jarosław had for years assisted Ukrainian war refugees arriving from Ukraine. Jarosław lies roughly 30 kilometres from the Ukrainian border in Subcarpathian Voivodeship. Polish-Ukrainian relations had been described in reporting as deteriorating in the months before the attack, with an earlier knife attack by a Ukrainian teenager in Wrocław on 1 August cited as prior context. An IBRiS poll cited in reporting found 67.2% of Poles supporting the deportation of Ukrainian men without legal work.
