“We have been saying right from when this story started that our experts are convinced that the deployment of the ABM system poses a certain threat to the Russian Federation,” presidential spokesman Dmitry Peskov said on Thursday.
"Measures are being taken to ensure the necessary level of security for Russia. The president himself (Vladimir Putin), let me remind you, has repeatedly asked who the system will work against?", Peskov said.
The response comes after NATO Secretary General Jens Stoltenberg reiterated the site is not a threat to Russia.
