Richard Goldstone, a former South African judge, has been effectively banned from attending his grandson's bar mitzvah which is to be held in Johannesburg next month.
Goldstone, who authored a UN report on the war crimes committed by Israel in the Gaza Strip, has been barred by the South African Zionist Federation (SAZF) from attending the event, South African and Israeli newspapers reported on Thursday.
"A very ugly feature of the response to the Goldstone report has been personal attacks like this on him and his family over a sustained period," Doron Isaacs, a Jewish South African, told Al Jazeera on Thursday.
"This should not be seen as an isolated incident."
