KFC apologizes after promotion tells Germans to mark Kristallnacht with crispy chicken

KFC is apologizing after a promoting a menu item as a way to commemorate Kristallnacht, the 1938 attacks by Nazis on Jews viewed by many as the start of the Holocaust. 

"It's memorial day for Kristallnacht! Treat yourself with more tender cheese on your crispy chicken. Now at KFCheese!," according to a translation from the BBC of a push notification sent on Wednesday to KFC app users in Germany. 

Soon after, three different screenshots of KFC's notification were posted on Twitter, drawing strong rebukes on social media.

"Absolutely hideous," tweeted Daniel Sugarman, director of public affairs for the Board of Deputies of British Jews. "Utterly speechless and repulsed," tweeted Arsen Ostrovsky, head of International Legal Forum, a pro-Israel legal organization.
