File photograph shows some of the 600 children, who had survived Auschwitz II-Birkenau, show their tattooed identification numbers. Some 7,000 prisoners, including more than 600 children and youths below the age of 18, were alive when the camp was liberated. On January 27, 2005, hundreds of survivors and dozens of world leaders will commemorate the 60th anniversary of the camp's liberation by the Soviet army and pay homage to the estimated 1.5 million people, mostly Jews, murdered there by the Nazis.
