Marchers hold up Israeli flags as they arrive in the death camp of Auschwitz-Birkenau to mark the annual Holocaust remembrance in Oswiecim, Poland, on Tuesday during the annual “March of the Living.” The event, which commemorates the 6 million Jews who perished in the Holocaust, was launched in 1988, drawing thousands of people from around the world, from Jewish youngsters to elderly Holocaust survivors. Organizers estimated that half of the 8,000 people who gathered this year were not Jewish. (Janek Skarzynski / AFP / Getty Images)
