KFC has apologized after it sent promotions to customers in Germany for its new cheesy chicken, urging them to celebrate Kristallnacht this week.
Kristallnacht or The Night of Broken Glass is widely seen as the start of the Holocaust, and shift from anti-Semitic rhetoric to violent, aggressive anti-Jewish measures.
The name is in reference to the thousands of shattered windows that littered the streets after the two-day period that saw 267 synagogues and thousands of other Jewish-owned businesses destroyed, as well as the deaths of 90 Jewish people.
The fast food restaurant sent an app notification Wednesday urging customers to celebrate the day with its new menu offering.
