German soccer team Schalke has unveiled a plaque outside its stadium with a ceremony to commemorate nine Jewish members and supporters who perished in the Holocaust.

Israeli singer Yael Izkovich opened the ceremony Wednesday, 80 years to the day after Adolf Hitler assumed power in Germany.

In front of about 200 guests, Schalke financial director Peter Peters said "it is our obligation to keep the memories alive. Schalke did not protect its Jewish members, sponsors, officials and athletes during the time of National Socialism."

The ceremony was also attended by Schalke general manager Horst Heldt, coach Jens Keller, and players Benedikt Hoewedes, Julian Draxler and Christoph Metzelder.

It was concluded by Rabbi Chaim Kornblum with a memorial prayer for the murdered Jews of Europe and a hymn of mourning.
