Pope Franjo said politicians who spread hatred towards gays, Roma and Jews reminded him of Hitler.
"It is no coincidence that the symbols that are typical of Nazism reappear," the pope said in his address to the international conference on criminal law.
He said that the speeches of some officials or of the government were reminiscent of Hitler's 1934 and 1936 speeches.
"Persecution of Jews, Roma and homosexuals today is typical and par excellence in a culture of rejection and hatred. It was done at the time, and it is happening more today," the Pope said.
Otherwise Pope Franjo did not name the politicians or states to which this criticism refers.
