Poland has held up a Ukrainian search at Łasków for months, Ambassador Vasyl Bodnar told Polish broadcaster RMF24, NV reported on 19 August. He says the eastern Polish village may contain the remains of civilians killed there by Polish underground forces in 1944.

The permit dispute is part of a much larger argument over how Ukraine and Poland remember the wartime killings of Poles and Ukrainians. Reciprocal searches resumed only recently after years of deadlock, giving both countries a way to recover and identify victims even as they disagree over historical responsibility. The latest delay tests that fragile progress while Poland remains Ukraine’s main route for Western arms and aid.

Bodnar says Ukrainian civilians were killed at Łasków in 1944 by the Home Army—Poland’s principal underground resistance force during the Nazi occupation—and the Peasant Battalions, an agrarian underground movement.

Bodnar appealed to Poland to issue "at least one permit" for searches on its territory. He said Ukraine systematically approves Polish requests in return. The ambassador blamed the holdup on unspecified “bureaucratic restrictions” and urged Warsaw not to leave the impression that Kyiv was obstructing the work.

In July, Bodnar said Poland’s Institute of National Remembrance had supported the Łasków application procedurally and that only approval from the regional monuments conservator remained. He expected work to start in August.

The institute said it had assisted with Łasków but was awaiting more documents for Ukraine’s separate applications concerning Sahryń and Przemyśl.

Past Polish-Ukrainian exhumations

Reciprocal work between Ukraine and Poland resumed only after Kyiv lifted a moratorium imposed in 2017. Ukraine had halted Polish exhumations in response to the destruction of Ukrainian memorial sites on Polish soil.

Ukraine will keep issuing Polish exhumation permits despite historical tensions. Dispute “causes joy in Moscow,” Kyiv says

A joint team exhumed the remains of 42 Polish victims of massacres by Ukrainian nationalists at Puzhnyky in western Ukraine in May 2025. Ukrainian researchers later searched for a suspected grave of up to 18 Ukrainian Insurgent Army fighters at Jureczkowa, Poland, but found none.

Ukraine granted further permits for Polish searches in 2026. Joint work at Uhly in Rivne Oblast found no mass grave, while exhumations began at Ostrivky and Volia Ostrovetska in July.

Historical grievances strain wartime alliance

The searches are the practical core of a broader dispute over wartime killings of Poles and Ukrainians. Competing interpretations of the Volyn tragedy and battles over Ukrainian Insurgent Army symbols have increasingly spilled into Polish politics and the streets.

Kyiv says it continues approving Polish grave searches while its own researchers wait to begin work in Poland.

Former Polish prime minister Jarosław Kaczyński accused groups in western Ukraine of desecrating remains and stealing WWII-era victims’ jewelry. The leader of the national-conservative Law and Justice (PiS) wrote on X on 14 August 2026 that his party would demand Polish government intervention.

Kaczyński’s claim comes amid growing anti-Ukrainian sentiment in Poland and a dispute with Kyiv over how Polish wartime victims are remembered. However, Kaczyński’s X post named no location and provided no public evidence, while authorized Polish-Ukrainian teams continue exhuming and reburying Polish victims.

“Illegal excavations at the sites of former Polish villages in Eastern Galicia are turning out to be real,” Kaczyński wrote, referring to a historical region now largely in western Ukraine.

He called the alleged looters “black diggers,” a term for people who dig through burials or archaeological sites for valuables. He said they were pilfering the graves of Poles killed in the World War II-era Volhynia massacres and alleged that local Ukrainian officials were allowing it.

Kaczyński said PiS would appeal to Poland’s state authorities, including the Foreign Ministry, and demand “explanations and a response.”

The evidence described by PiS has not been made public. Onet reported that it was unclear which incidents he meant and that neither government had responded at the time. PiS spokesperson Rafał Bochenek later told the publication Interia that citizens had sent photographs allegedly showing damaged graves and listings for excavated objects. Interia published neither.

Polish-Ukrainian teams continue authorized exhumations

Meanwhile, Poland’s Institute of National Remembrance (IPN), the country's state historical institute, said Ukraine authorized its latest excavations at Ostrówki and Wola Ostrowiecka in Volyn.

From 13 July to 7 August, Polish and Ukrainian specialists recovered 55 victims, including 26 children. They also secured more than 300 personal items and pieces of clothing. The remains are due to be buried at Ostrówki cemetery on 30 August.

The excavation followed a wider thaw. Ukraine lifted its moratorium on Polish searches, while joint teams exhumed and reburied 42 people at Puźniki in 2025. Both countries have exchanged lists of sites for further searches.

Historical disputes deepen the Polish-Ukrainian rift

Relations between Kyiv and Warsaw worsened after Ukraine gave a military unit the honorary title “Heroes of the Ukrainian Insurgent Army (UPA)."

The UPA fought for Ukrainian independence but is held responsible in Poland for the World War II-era massacres of Polish civilians. Polish President Karol Nawrocki later stripped President Volodymyr Zelenskyy of the Order of the White Eagle, Poland’s highest state honor.

Violence is also rising on the Polish streets. Reports of suspected hate crimes against Ukrainians in Poland rose by more than 30% in the first half of 2026, even as anti-xenophobic voices became more visible online. Kaczyński’s claim adds an unverified criminal allegation to the dispute.
