Survivors of the Nazi concentration camp of Bergen-Belsen gathered Friday, marking the 60th anniversary of their liberation by British troops

Some 100,000 prisoners from 40 countries had died in the camp, located 100 kilometers south of German city of Hamburg.

"You have to keep telling people about the horrors of the Holocaust. It's the only way to make sure something like that never happens again," US camp survivor Marion Blumenthal told German schoolchildren at the site of the camp. 
A photo dated April 1945 of the corps of the dead fellows piled in Bergen-Belsen concentration camp. 

Blumenthalat later become an author and described in her book how she, as a 10-year-old girl, and her family were freed from the camp. Parties of young people from Israel and Eastern Europe also listened to her speech.

An official memorial ceremony will be held on Sunday when officials from the state of Lower Saxony will attend the ceremony and talked with a group of young people from nine countries.

Bergen-Belsen camp was liberated by British troops on April 15, 1945.
