Norwegian police on Thursday responded to a threat made by telephone against the Nyhamna gas processing plant, one of Europe's largest energy export facilities, and later said the incident had been resolved.

"The situation has been resolved," police operations leader Per Aage Ferstad said in a statement, adding police did not believe the incident had posed a real danger to the plant. 

A suspect had been identified and was known to have made similar threats in the past, police said.

The Norwegian military Home Guard has been guarding the facility since authorities boosted security at Norwegian oil and gas installations in the wake of the explosions on the Nord Stream pipelines on September 26.
