The Polish Ministry of Defence has denied reports by RBC-Ukraine that it blocked the transfer of a military aid package to Ukraine due to the Lviv Regional Council's decision to declare 2027 the "Year of the Ukrainian Insurgent Army" (UPA). The UPA was a far-right Ukrainian nationalist insurgent group that collaborated with Nazi Germany during World War Two, and committed massacres against poles in Volhynia and Eastern Galicia, which Poland recognises as a genocide. The Ukrainian Ministry of Foreign Affairs called the decision by the Lviv Regional Council counterproductive.
