The promotional message that was sent to customers in Germany urged them to commemorate Kristallnacht with chicken.

More than 90 people were killed in a series of Nazi attacks on the country in 1938.

It's believed to be the beginning of the Holocaust.

An error in our system was blamed for the message's insensitivity.

On memorial day for Kristallnacht, the fast food chain sent an alert. It's a good idea to treat yourself to more cheese on your chicken. The place is now at KFCheese.

An apology was sent around an hour later.

We will make sure that this doesn't happen again by checking our internal processes. The message apologized for the error, according to the report.

Germany takes the 9 November anniversary of Kristallnacht seriously, with numerous memorial events and discussions planned to reflect the Nazis' murder of six million Jews.

The original message from Kentucky Fried Chicken was described by Daniel Sugarman as "absolutely hideous".

The associate director of European affairs at the Anti-Defamation League commented on Kristallnacht. Shame on you.

The message was blamed on a bot by Kentucky Fried Chicken Germany.

The fast food chain said the push notification was linked to the calendar.

App communications have been suspended while an examination of them is carried out, and it apologized for the "unplanned, insensitive and unacceptable message".

We understand and respect the history of this day and are committed to equity, inclusion and belonging for all.
