A young person places daffodils during observances of the 72nd anniversary of the Warsaw Ghetto Uprising, in front of the monument to the Heroes of the Ghetto, in Warsaw, Poland, on Sunday, April 19, 2015. A few hundred Jews at the ghetto rose with arms on April 19, 1943 against the Nazi Germans who began to transport hundreds of thousands of ghetto residents to the Majdanek death camp. Daffodils were the flowers that Marek Edelman, one of the Warsaw Ghetto uprising leaders, who died in 2009, used to lay at the fighter's monument during memorial ceremonies.
