Hundreds of Nazi concentration camp survivors gathered in Berlin on Sunday, marking the 60th anniversary of their liberation.

In Sachsenhausen camps north of Berlin, German Foreign MinisterJoschka Fischer reiterated the obligation of Germans to remember the Nazi Crimes. Germans "can never and will never" escape the responsibility, said Fischer, adding that the memory of those crimes must be kept alive for Germany's future generations.

Some 200,000 prisoners were held here between 1936 and 1945 until the Soviet Red Army liberated them on April 22, 1945.

In the Nazi concentration camp of Bergen-Belsen, 100 kilometers south of German city of Hamburg, president of Germany's Central Council of Jews Paul Spiegel called for more strength to fight against the right-wing extremism and anti-Semitism.

"Anti-Semitism and the discrimination of minorities have posed an ever serious danger not only in Germany but also in many other countries," Spiegel said.
