For almost four years the ABC's Jerusalem based correspondent Matt Brown has been reporting on the Israeli/Palestinian divide, but for this Foreign Correspondent story he focuses on violence by Jewish immigrants from the former Soviet Union.

He finds ultra-orthodox Jews, Asians and migrant workers being attacked on Israeli streets by a gang of young neo-Nazis.

The police, initially at least were seemingly unwilling or unable to take action.

Brown sets out to find out what motivates Ivan Kuzmin, a young Ukrainian Jew, charged with assault and incitement to racism.

Kuzmin's family migrated to Israel 10 years ago hoping for a better life free of discrimination. But Ivan still didn't fit in."There they called me things like dirty Jew... And here they called me stinky Russian."

Despite having a grandmother who survived the Jewish Holocaust in Europe, Kuzmin joined other young immigrants in a neo-Nazi gang called Patrol 36, which regularly bashed people senseless. They were so proud of their actions they videotaped their attacks.
