"There is a “significant risk” Russian could target critical infrastructure in Europe or North America, including gas pipelines and internet cables, as part of its confrontation with the West over Ukraine, a senior NATO intelligence official warned.
David Cattler, NATO's assistant secretary general for intelligence and security, told reporters Russia was “actively mapping” the infrastructure of Ukraine’s allies both on land and on the seabed.
Moscow's military and civilian intelligence services had “considerable resources” that Vladimir Putin could deploy for surveillance of infrastructure, “including the use of civilian ships and so-called spy ships,” Cattler added."
