People in Warsaw mark 75th anniversary of Warsaw Uprising Thousands gather in the Warsaw city center near the iconic Palace of Culture and Sciences to mark the 75th anniversary of the Warsaw Uprising in Warsaw, Poland. The Warsaw Uprising was a brutally suppressed attempt by the underground Polish army to liberate the city from German occupiers. The event has been particularly contentious this year as it was expected that many nationalists would join the anniversary event and cause unrest. IMAGES
