Secretary General Jens Stoltenberg said after the meeting that Russia's SSC-8 missile system is a significant risk to the security of the Alliance.
The US began the process of exiting the treaty earlier this month in response to Moscow's deployment of the 9M729 missile, prompting Russian Federation to announce its own withdrawal. Mr. Stoltenberg stressed that Russian Federation still has a six month window to come back into compliance with the INF Treaty and it should take this opportunity.
"Any steps we take will be coordinated, measured and defensive, and we do not intend to deploy new ground-based nuclear missiles in Europe", Stoltenberg told reporters at North Atlantic Treaty Organisation headquarters in Brussels on the eve of a meeting of allied defense ministers.More news: China, Russia pose threat to USA space capabilities: Pentagon report

"Then of course we have a wide range of other options, conventional and other options, but I will not speculate on them now", Stoltenberg said. North Atlantic Treaty Organisation allies made a decision to deploy US cruise and Pershing 2 ballistic missiles in Europe in 1983 as negotiations with Moscow faltered over its stationing of SS-20 missiles in Eastern Europe.
German Defence Minister Ursula von der Leyen said a "broad mix of measures" was being considered, and unexpectedly - given Berlin's softly-softly approach on the INF issue - she refused to rule out the deployment of nuclear missiles.More news: Watch Pregnant Amy Schumer Make a Gender Announcement
The top US envoy to the North Atlantic Treaty Organization said Washington was open to a broad treaty with Russian Federation to curb the proliferation of nuclear weapons while also warning Turkey not to purchase a new arms system from Moscow.
"Moscow continues to develop and deploy several battalions of the SSC-8 missile", Mr Stoltenberg said. "And we don't have any intention to deploy new nuclear land-based weapon systems in Europe".
While Washington and Moscow are at odds over the INF, the treaty does nothing to constrain China, whose fast-growing military depends on medium-range missiles as a key aspect of its defense strategy.More news: Mars One Is Bankrupt And Down For The Count
He accused the United States of abandoning the agreement "to free itself of any constraints in the arms sphere (and) gain absolute military superiority", in a column published by the Russian newspaper Vedomosti.
