The Holocaust is a grim reminder that Jews must be active in stopping genocide anywhere in the world, Sen. Charles Schumer warned yesterday at a candlelit ceremony in lower Manhattan marking Holocaust Remembrance Day.

"Thinking of the Holocaust should move us to fight other genocides as strongly as we can," he told more than 1,000 people - including survivors of the Nazi death camps - at the Museum of Jewish Heritage in Battery Park.

Former Secretary of State Henry Kissinger recalled how 13 relatives were killed because they didn't believe Germany would carry out Hitler's maniacal plans.

"It is something one can never forget," he said.

Death-camp survivor Ray Kaner, 78, of New York recalled the horrors she witnessed at Auschwitz when she was 11.

"A lot of people say it never happened, and the only way to respond is to go and tell your story," said Kaner, whose parents and two brothers were killed.
