The ceremony at Ossuve saw the unveiling of monuments to three high-ranking military officials who died in a plane crash outside Smolensk, Russia in 2010, which Macierewicz has previously characterized as a deliberate act of 'terrorism' against Poland by Russia.
Speaking at the unveiling ceremony, Macierewicz noted that the officers who died in the crash "were faithful to the president of Poland…flying to Katyn to pay tribute to those who lost their lives in the Soviet genocide."
In July, the Polish parliament officially recognized the crimes of Ukrainian nationalists against Polish civilians in Volyn during the Second World War as a genocide. Macierewicz soon claimed that the Soviet Union was to blame for that event as well, suggesting Moscow had "used" the Ukrainian fascists to organize the anti-Polish genocide.
Late last month, as a goodwill gesture to Warsaw,lawmakers from the Russian Duma proposed a bill which would officially recognize the crimes committed by the Ukrainian fascists a 'genocide'.
