Russia threatened to aim nuclear missiles at Danish warships if Denmark joins NATO's missile defense system, in comments Copenhagen called unacceptable and NATO said would not contribute to peace.

Moscow opposes the system, arguing that it could reduce the effectiveness of its own nuclear arsenal, leading to a new Cold War-style arms race.
