By Barbara Erling and Kuba Stezycki OSWIECIM, Poland (Reuters) -Auschwitz survivors warned of the dangers of rising antisemitism on Monday, as they marked the 80th anniversary of the liberation of the Nazi German death camp by Soviet troops in one of the last such gatherings of those who experienced its horrors.

While the number of survivors in Israel dropped to 123,715 last year, a rising trend of Holocaust memorials in the Muslim world provide 'a small amount of light'

At Auschwitz, the Germans left behind barracks and watchtowers, the remains of gas chambers and the hair and personal belongings of people killed there. The “Arbeit macht frei” (work will set you free) gate is recognized the world over.
