LOHHEIDE, GERMANY - APRIL 26:  Flowers and stones lay on and in front of the gravestone of Margot Frank and Anne Frank after a ceremony to commemorate the 70th anniversary of the liberation of the Bergen-Belsen concentration camp at the former camp site on April 26, 2015 near Lohheide, Germany. An estimated 70,000 inmates died at the hands of the Nazis at Bergen-Belsen during World War II, including Jews and Soviet prisoners of war. Most famous among the victims is Anne Frank, who died at Bergen-Belsen of typhus shortly before the liberation by British troops in April, 1945.  (Photo by Alexander Koerner/Getty Images)
