German Foreign Minister Heiko Maas said the expiry of the Intermediate-range Nuclear Forces (INF) Treaty on Friday meant Europe was "losing part of its security."
The landmark arms control accord, signed in 1987 by US President Ronald Regan and Soviet leader Mikhail Gorbachev, bans medium-range land-based missiles, which are capable of reaching Russia from Western Europe and vice versa.
In February, the United States formally announced it would withdraw from the pactafter accusing Russia of developing weapons that it said violated the terms of the treaty. Moscow responded by saying it would pull out as well.
