Russia’s Federal Security Service released newly declassified documents this week detailing the mass killings of Polish civilians by the Ukrainian Insurgent Army (UPA) during World War II. The timing was deliberate: Poland marks its National Day of Remembrance on Saturday, honoring victims of the ethnic cleansing campaign in the Volhynia region between 1943 and 1944, which claimed at least 100,000 civilian lives according to Polish estimates. Poland recognizes the events as genocide, while modern-day Ukraine has celebrated UPA fighters as national heroes — a point of ongoing tension between Kyiv and Warsaw that Moscow appears keen to exploit.
