(JTA) — More than 80 headstones at a Jewish cemetery in Denmark were overturned and vandalized with green paint.

The damage at the Ostre Kirkegard cemetery in the town of Randers in western Denmark was reported on Saturday, though it is not known when the vandalism took place. The green paint was dashed on the headstones and did not form any words or symbols, the French news agency AFP reported.

Burials in the cemetery date back to the early 19th century.

Also on Saturday, a family in Silkeborg, Denmark, located about 28 miles from Randers, awoke to find a large sticker bearing a yellow Star of David with the word “Jude,” German for Jew, stuck to their mailbox. Saturday was the 81st anniversary of Kristallnacht, a 1938 pogrom against Jewish homes, synagogues and Jewish owned-owned businesses in Germany and Austria.

The Danish Ekstrabladet reported the incident, and photos of the mailbox circulated on Facebook.

Ella Chievitz, who is Jewish and has dual Danish and Israeli citizenship, said in a post on Facebook that she is  “shocked and angry.” Her husband is Christian, but serves as chairman of the Israeli-Denmark Association.
