Turkey's plans to deploy Russian S-400 missile system 'worrying' - NATO

The consequences of Turkey's plans to deploy the Russian S-400 missile defence system are worrying, as Washington has made clear it would impose sanctions, NATO Secretary General Jens Stoltenberg said on Monday in a news conference. Speaking in Ankara following a meeting with Turkish Foreign Minister Mevlut Cavusoglu, Stoltenberg said NATO would want to avoid conditions where allies impose sanctions on one another.
