OSWIECIM, Poland (AP) — The 80th anniversary of the liberation of Auschwitz by Soviet troops is being marked on Monday at the site of the former death camp, a ceremony that is widely being treated as the last major observance that any notable number of survivors will be able to attend.

In all, the Nazi regime murdered 6 million Jews from all over Europe, annihilating two-thirds of Europe's Jews and one-third of all Jews worldwide. In 2005, the United Nations designated Jan. 27 as International Holocaust Remembrance Day.

World leaders rubbed shoulders with 56 survivors of Hitler's death camp as they marked 80 years since its liberation.
