On April 20, 2026, a controversial event was held at the Katyn massacre site, organized by the Russian Military-Historical Society, which is associated with an adviser to President Putin.
The Katyn massacre, where approximately 22,000 Polish officers and intelligentsia were killed by Soviet secret police in 1940, remains a sensitive historical issue.
The display has drawn considerable backlash, reflecting the ongoing historical and political tensions between Russia and Poland.
