According to The Daily Telegraph, the men's families were allowed to settle in Israel under the Law of Return, meaning that they all had at least one grandparent with a Jewish mother, although none of them were Jewish according to the Jewish law.
Enligt The Daily Telegraph var männens familjer tillåtna att bosätta sig i Israel enligt lagen om återvändande, vilket innebär att de alla hade minst en farförälder med en judisk mor, även om ingen av dem praktiserat religionen.
