挪威称其面临恐怖袭击威胁

Norway's intelligence service says its received information about an imminent "concrete threat" against Norwegian targets from fighters connected to the conflict in Syria.

Benedicte Bjoernland is the head of Norwegian security service PST.

"The PST receives this kind of information from time to time from our partners, but turns out not be true, after we investigate to confirm or dismiss the information. In our initial investigations in this particular case, the credibility was strengthened."

Bjoernland says they don't have any specifics about what may be targeted.

"We also have information that indicates a terror act will be conducted in Norway soon, probably within the next few days. We have no information on who, how, or what target and in which way a possible attack could be carried out."

A PST's assessment last month has suggested around 50 people have traveled to Syria from Norway as foreign fighters, half of whom have now returned to Norway.
