Police said today marble ornaments were smashed off 12 graves, while vandals also tried to remove the tombs' heavy marble covers.
Foreign Minister Evangelos Venizelos promised that police would do "whatever is humanly possible" to arrest the vandals. David Saletiel, head of the Jewish Community of Thessaloniki, told The Associated Press that a caretaker discovered the "tragic spectacle" yesterday.
The northern port city, Greece's second-largest, hosted the country's most populous Jewish community until World War II. The community was centuries old.
