Increased Russian Military Activity in Arctic Raises Concerns for Norway.

Norway is increasing naval patrols near undersea gas pipelines off its coast due to a growing Russian threat in the Arctic. The Royal Norwegian Air Force has released videos showing Russian attack submarines and planes operating near Norway's natural gas pipelines, which represent a vital energy lifeline for Europe. The Russian military has invested heavily in its submarine fleet, making its boats quieter and more lethal. Norway, with more than 5,000 miles of pipelines, is now supplying 30 to 40% of Europe's natural gas needs, up from about 20% before the Ukraine invasion.
