The anniversary of Kristallnacht, a series of anti-Jewish attacks by the Nazis, was marked by a message from a fast food chain.

Customers in Germany were horrified to receive the push notification from the fast food restaurant yesterday, on the anniversary of the 1938 attacks when Nazis orchestrated and carried out the destruction of thousands of Jewish homes, businesses, and schools.

It is memorial day forKristallnacht. It's a good idea to treat yourself to more cheese on your chicken. It's now at KFCheese.

The second notification apologized for Kristallnacht and promised to check the internal process.

The initial offensive alert was blamed on a "semi-automated content creation process" that is linked to a calendar of national holidays.

The company told Newsweek that it had paused app communications and would review processes to make sure it didn't happen again. An on-the-record response was not provided by Kentucky Fried Chicken.

The 84th anniversary of Kristallnacht was marked by the release of new images. The question of why brands would want to hear from them on a holiday or anniversary has been raised by the promotion of Kentucky Fried Chicken.
