Poland and Ukraine commemorate Volhynia massacre's Bloody Sunday
Poland and Ukraine mark July 11, 1943, when the Ukrainian Insurgent Army began mass killings of Polish civilians in Volhynia, resulting in up to 100,000 victims.

Poland and Ukraine are commemorating the so-called Bloody Sunday, a tragic event during World War II. On July 11, 1943, the Ukrainian Insurgent Army (UPA) launched a series of mass attacks against Polish civilians in the Volhynia region, marking the beginning of the Volhynia massacre. The violence continued until 1945.
Historians estimate that up to 100,000 ethnic Poles were killed in these events. The massacre left deep scars in bilateral relations and remains a painful historical issue. Today, memorial ceremonies are held in both countries to honor the victims and remind the public of the scale of the tragedy.
