Translated from Fyens:

Centrally placed sources told the Norwegian television and radio station NRK that militants who probably sympathize with the Islamic State this summer planned to kill a whole family with knives, film it and publish it as a warning….

In July, Norway was under a terror alert, which included extra staff at all border crossings and the fact that cars, planes and trains were searched more than usual. Also, the Jewish synagogue in Oslo was closed….

The extremists were planning to break into a house, cut the throats of all the residents and post video of the atrocity on the Internet.

It was supposed to be a random house. …

Sources have told the newspaper Dagbladet that four people from the Islamic State were heading for Norway, and that it led to the terror alert. The four landed in Athens in July, but since then police lost track of the group.
