Members of the Polish Army take part in a celebration by the Monument to the Ghetto Heroes during the Holocaust Remembrance Day on January 27, 2021 in Warsaw, Poland. January 27, the day the Auschwitz concentration camp was liberated in 1945, is observed as International Holocaust Remembrance Day, although this year many memorials and educational events will be held online due to the COVID-19 pandemic.
