Synagogues and media houses were marked with threatening stickers

The night between November 9 and November 10, 1938, the Nazis carried out violent attacks against Jews in Germany. About 400 Jews were killed or forced to commit suicide. Tens of thousands were arrested and taken to concentration camps and shops and synagogues burned down. The event is called the Crystal Night.

The night before Sunday, exactly 81 years later, stickers with so-called "Jewish stars" were set up at synagogues, Jewish premises and several media houses in Sweden, Denmark and Norway. A "Jew star" is a Star of David on a yellow background with the word "Jew" written inside, a symbol the Jews were forced to wear on their clothes in Nazi Germany and in other countries occupied by the Nazis.

"It is a worrying development that the right-wing extremists have the ability to coordinate this in several different countries simultaneously," says Aron Verständig, chairman of the Jewish Central Council and the Jewish Assembly in Stockholm.

Verstig confirms that the stickers have been installed at Jewish premises and synagogues in Stockholm, Gothenburg and Norrköping. Police from the ward have reported the events and informed their members.

- People are very upset. We have seen many activities targeting the Jews of Sweden - both individuals and organizations. Now you have to take hold of these groups that have grown stronger. It is a very serious attack on democracy.

Several media houses were also exposed to scribbles and that "Jewish stars" were erected on facades, including Norrbotten's Media in Luleå and Corren in Linköping.

- A media house cannot accept such a doodle. It should not happen in a media landscape that rests on democratic grounds. This is unacceptable, says Öst Media's CEO and publisher Anna Lindberg.

A Danish Jewish couple, who are active in several Danish-Israeli associations, have received one of the threatening stickers put on their mailbox, reports Danish BT.

- It's getting too close. Who can come up with something like that. It is a symbol of murder, death and destruction, the vulnerable woman tells the newspaper.
