On January 27th, 1945, the Auschwitz concentration camp in Nazi-occupied Poland was liberated by Soviet troops. Some 1.1 million people were killed there between 1940 and 1945. More people died at Auschwitz than at any other Nazi concentration camp. Soviet soldiers found about 7 thousand starving prisoners alive in the camp.
About 300 survivors returned to the site for ceremonies marking the 70th anniversary. Most were children at the time of the liberation, but are now elderly and this may be the last significant Auschwitz remembrance of their lifetimes.
