** FILE ** In this April 19, 1943 file photo, a group of Jews, including a small boy, is escorted from the Warsaw Ghetto by German soldiers. The family of a Polish social worker Irena Sendler who is credited with rescuing 2,500 Jewish children from the Nazis during the Holocaust says she has died. Sendler's daughter, Janina Zgrzembska, says her 98-year-old mother died Monday, May 12, 2008, morning in a Warsaw hospital. Sendler organized the rescue of Jewish children from the Warsaw Ghetto during Nazi Germany's brutal World War II occupation. (AP Photo)
