Germany ? Remains believed to be of 34 Jews who died doing slave labor for the Nazis were re-interred with full religious rites Thursday at the U.S. Army airfield where their mass grave was discovered.

Tel Aviv chief rabbi Israel Meir Lau, a Holocaust survivor who was formerly Israel’s chief rabbi, was among about 300 people who attended the ceremony at the airfield, next to Stuttgart’s airport.

Lau joined several other speakers in using the occasion to denounce remarks made Wednesday by Iranian President Mahmoud Ahmadinejad that the Holocaust is a “myth.”

“We must invite him to Stuttgart and show him that it is no myth, but instead a fact that is a painful and unforgettable part of our lives,” Lau said.

The remains were found in September during construction work at the airfield. They are believed to be the bodies of Jewish inmates from part of the Natzweiler-Struthof concentration camp who were used as slave laborers between November 1944 and February 1945.

Some 119 people from 12 European countries died of hunger and typhus during that period, said Guenther Oettinger, governor of the southwestern state of Baden-Wuerttemberg.

Nineteen bodies were cremated at the time, and another 66 corpses were found buried nearby in October 1945, shortly after World War II ended.
