North Atlantic Treaty Organization (Nato) allies have put forces on standby and sent ships and fighter jets to bolster Europe's eastern defences as tensions soar over Russia's military buildup around Ukraine, the alliance said Monday.
"Nato will continue to take all necessary measures to protect and defend all Allies, including by reinforcing the eastern part of the Alliance. We will always respond to any deterioration of our security environment," Nato Secretary General Jens Stoltenberg said in a statement.
