A NEO-NAZI organiser from Victoria has been working as a private military contractor in Afghanistan, mocking locals and holding secret ceremonies commemorating the deaths of German soldiers in World War II.

Kenneth Stewart, 36, has worked as a military-trained paramedic, accompanying aid workers around Afghanistan. His Facebook page shows a swastika flag in his room in Kandahar, and another picture shows him surrounded by Afghans he refers to as ''my nignogs'' with a friend adding the comment ''it's lovely to see a white man back in control of the subhuman''. On Stewart's Facebook page he regularly makes disparaging comments about Afghans, Aborigines, Jews and others.

Kenneth Stewart's Facebook image shows him on Remembrance Day in Kandahar.

He has worked as a medic for several aid groups based in Kandahar, including the United Nations Development Program.

The Age made several attempts to contact Mr Stewart, but received no reply.
