NATO chief Jens Stoltenberg warned about increased activity by Russian submarines in the Mediterranean Sea and Atlantic Ocean, Politico reports.
“Russia has massively invested in its marine capability, especially in submarines,” the military alliance’s secretary-general said.
“Russia’s submarine activity is now at its highest level since the Cold War,” he said, pointing to thirteen additional submarines since 2014. Russian submarines are operating all over the Atlantic, as well as “closer to our shores,” he said.
