Haris Doukas, the mayor of the Greek capital city Athens, on Sunday responded to criticism from Israel’s chief diplomat to the country, Ambassador Noam Katz, with charges of genocide against the Jewish state.

In an interview with Greece’s Kathimerini newspaper, Katz said that antisemitic vandalism in Athens had generated concerns among Israeli tourists. He charged that Doukas, a member of the Socialist PASOK party, had failed to counter the “organized” groups responsible for the hateful graffiti. In one example, on July 12, six individuals entered an Israeli restaurant in Athens and sprayed black paint on walls and tables in addition to dropping pamphlets. They spray-painted graffiti with slogans such as “No Zionist is safe here” and posted a sign on one of the restaurant’s windows that read, “All IDF soldiers are war criminals — we don’t want you here,” referring to the Israel Defense Forces.

Doukas pushed back on the accusation, lashing out against Israel.
