Leo, the first U.S. pope, appealed to world leaders “to always remain vigilant, so that the horror of genocide may never again fall upon any people”.
International Holocaust Remembrance Day, an annual commemoration established by the United Nations, was marked on Tuesday.
Relations between the Catholic Church and Judaism have improved in recent decades, after centuries of animosity.
Leo, like his predecessor Pope Francis, has condemned antisemitism several times since becoming the leader of the 1.4-billion-member Catholic Church last May.
