Three Jewish brothers are hunting for answers as they suspect their father may have fought Nazis during and after World War Two.

Jack, Sam and Rabbi Jon Green have long suspected that their father, Boris Green, might have been responsible for the death of Nazis in Australia after the family fled there to escape the trauma of the war.

Speaking to GB News Breakfast, Jack said: "There's a lot of circumstantial evidence. As my brother Sam said in the film, there was a war after the war.

"Jack and my experiences were very different. We're 15 years apart in age he is 15 years older."

Jack added: "It became quite a shock to me when I heard this family story that he'd possibly been involved with some action against Nazi collaborators who would also come to Australia after the war. "
