A leading cardiac surgeon has returned to work seven weeks after his hospital launched an investigation into his comments during a meeting of Palestine Justice Movement Sydney.

Professor Peter Macdonald, head of the transplant unit at St Vincent’s Hospital Sydney, was on leave when a video of the meeting surfaced on social media in late August. 

As a member of the audience, he stood up and asked a discussion panel a question, suggesting that Mossad, Israel’s intelligence agency, was involved in two incidents of anti-Semitism in Australia.

“I learned this week that Iran was behind the ‘terrorist’ attacks, the anti-Semitic terrorist attacks in Sydney,” using air quotes when he said “terrorist”.
