Norway isn't too worried about Islamic terrorists sneaking into the country, but about the surge of far-right domestic extremism caused by the arrival of a large number of refugees, the report said.
These lunatics, fueled with anger and hatred, are capable of carrying out devastating terrorist attacks against refugees and everyone who isn't in line with their ideology.
"Resistance against immigration is one of their [far-right groups] pivotal causes and an important mobilization factor for this environment," the police report said, as cited by Reuters.
Meanwhile, Norway is getting ready to receive between 16,000 — 20,000 asylum seekers this year only.
Unless the refugee crisis isn't addressed properly, there would be a surge of far-right domestic extremism across the entire continent, European Commission Vice President Frans Timmermans said earlier this week.
