The man making the claim told NRK: “There are cells awaiting orders, and it is more than one group.”
NRK met the defector at a secret location in Turkey, near the border to Syria. The man claimed to have a background as a special soldier for Isis, and he defected from the terrorist group a few months ago.
He specifically said he had heard about people representing Isis in Sweden.
The defector said to NRK: “I received a call from a friend who got threats from Isis in Sweden.”
The man explained that the cells in Europe haven't necessarily been involved in the war zones of Syria and Iraq.
PST (Norwegian Police Security Service) refused to comment on the possible existence of Isis sleeper cells in Norway.
