The Algerians arrested in Italy are not the only potential terrorists in Norway, security forces said Thursday.
"We know that there are persons in Norway today that can be linked to the terrorist network abroad," Martin Bernsen, information adviser at the Norwegian Police Security Service (PST) told Aftenposten.no.
The PST will not disclose how many persons they are referring to, or how many different nationalities are involved.
Bernsen denied that the PST was not aware of the suspects arrested by Italian police on suspicion of terrorism, as Norwegian news agency NTB reported on Thursday.
"We knew about this case in advance. More than that we cannot say," Bernsen said.
Asked if the PST had cooperated with Italian police in this matter, Bernsen would only say that the PST has a close cooperation with the security services of other Nordic and some European nations.
Bernsen said that the PST considered the threat level in Norway to be unchanged at 'moderate' after the arrests in Italy.
