Watch a live broadcast from Oswiecim, Poland, where a commemoration ceremony is taking place to mark 77 years since the liberation of the Auschwitz-Birkenau concentration camp on Holocaust Remembrance Day.
Due to COVID-related restrictions, only a small group of guests will be present at the ceremony which focuses on the spring of 1942, when the mass extermination of prisoners in Auschwitz began.
The camp was operated by Nazi Germany from May 1940 through January 1945, when it was liberated by Soviet forces. At least 1.3 million people (according to other estimates - up to 1.5 million), mostly Jews, were killed at the camp.
