Norway police on 14 October investigated reports of a drone flying over the Kaarstoe gas plant in southwest Norway on 13 October, while, in Arctic Norway, a Russian/Israeli citizen was arrested when police found two drones in his car.
The Norwegian military Home Guard has been posted at Kaarstoe and other major energy export facilities since authorities boosted security at Norwegian oil and gas installations after the 26 September Nord Stream leaks.
At 2130 local time (1930 GMT) on Thursday, the military posted at Kaarstoe reported that they had seen a drone flying in the vicinity of the plant, police official Kjetil Lussand said.
In a separate incident, a Russian/Israeli citizen was arrested at the Storskog border crossing between Norway and Russia on 13 October after police found two drones and several data storage units in his car during a routine check.
