Footage shows a set of US B-52 bomber jets joined by Nato allies in a show of strength over Europe.
In a tweet, NATO Air Command said: "The B-52s are training with Allied Air Forces during their BTF mission strengthening our Euro-Atlantic partnership."
It comes after two American bombers were intercepted by a Russian fighter jet over the Baltic Sea.
On an earlier occasion, a US drone was forced down after a Russian aircraft carried out a “reckless” manoeuvre, according to the Pentagon.
