Norwegian intelligence authorities say the Scandinavian country "likely" will be threatened or an act of terror will be attempted in Norway within the next 12 months.

The Joint Counter Terror Center says the Islamic State group, among others, has called for terror acts against countries that are part of the U.S.-led alliance against the group.

Norway has said it will send 120 soldiers to join the international campaign against Islamic militants in Iraq and help train local troops there.

The assessment says military staff, police and political decision-makers could be "exposed."

Wednesday's assessment was not as high as in July, when the domestic intelligence agency said it had information about an imminent "concrete threat" from people with links to Islamic fighters in Syria. The threat level eventually was downgraded.
