Some 250 Germans have been joined by dozens of Hungarians on a five-day walk along the route taken by tens of thousands of Hungarian Jews who were marched to Germany and Austria as forced laborers at the end of World War II. Many of them died.

Among those taking part in the March of Life between Hungary's western border with Austria and Budapest were grandchildren of those involved in the Holocaust, seeking atonement. Some 550,000 Hungarian Jews died in the Holocaust.

Barbel Pfeiffer's grandfather helped build electrical fences and the electrical wiring of gas chambers at the Auschwitz death camp.

"Words cannot undo the events of the past, but we regret what happened with all our hearts," Pfeiffer said during Friday's remembrance at the Federation of Hungarian Jewish Communities.
