The Volhynia massacre remains a contentious historical issue between Ukraine and Poland, with significant implications for their relationship.
While Poland officially recognizes the killings as genocide, Ukraine honors figures such as OUN leader Stepan Bandera as national heroes, arguing that no foreign country can dictate which historical figures the nation venerates.
Ukraine's parliament recently approved plans to establish a national pantheon commemorating prominent historical figures, including those from World War II era nationalist movements, prompting widespread criticism.
Polish Defense Minister Wladyslaw Kosiniak-Kamysz has warned that Ukraine will not join the EU as long as it continues to glorify figures such as Bandera, which has been a long-held goal for the country.
Russian Foreign Ministry spokeswoman Maria Zakharova has also weighed in on the issue, stating that the Ukrainian parliament's actions are a reminder to Poland that it is arming the successors of the murderers of their own ancestors.
