Edit: It was his grandson: Addressing a large audience, Mandela said that the Nation-State Law passed in 2018 declaring Israel to be the historical homeland of the Jewish people “confirmed what we have always known to be the true character and reality of Israel: Israel is an apartheid state”.

You’re quoting his grandson…Mandela died in 2013

> "As I listened to the Arab League and as I listened to colleagues from Palestine, its sounds like this plan has been consulted without all the people that matter and it sounds like a Bantustan type of construct."

You’re quoting the South African President Cyril Ramaphosa who spoke in 2020.

Again, Mandela died in 2013.

It is not in contention that Mandela supported Palestinians. Though I cannot find evidence that he referred to the Israel conflict as apartheid.

You're right, I hadn't noticed, thanks for pointing it out.

I looked some more and found nothing. Criticism of Israel, yes, but not using that exact word.

I'm sorry. It seems that this didn't happen. One source of this false information might have been a satirical letter written by El Fassed which was signed by Mandela. The satire being apparent on the original publication but then picked up by others as a real letter.
