MOSCOW (AP) — Russia’s defense minister says the military will conduct regular long-range bomber patrols, ranging from the Arctic Ocean to the Caribbean and the Gulf of Mexico.

Sergei Shoigu’s statement comes as NATO has reported a spike in Russian military flights over the Black, Baltic and North seas as well as the Atlantic Ocean. It reflects Moscow’s increasingly tough posture amid tensions with the West over Ukraine.

Shoigu said Russian long-range bombers will conduct flights along Russian borders and over the Arctic Ocean. He added that “in the current situation we have to maintain military presence in the western Atlantic and eastern Pacific, as well as the Caribbean and the Gulf of Mexico.”

He said that the increasing pace and duration of flights would require stronger maintenance efforts.
