A Jewish gravestone in a cemetery in the New Zealand town of Wanganui has been attacked in one of the worst cases of grave desecration the city has seen, according to a report by a local newspaper. The headstone in the Jewish section of the cemetery had a swastika painted on it and looked as if it had been attacked with a sledgehammer, a city council official said. The vandalism was discovered when the area was checked after several Jewish graves were desecrated in the capital Wellington last month.
