Russia tells US that its counterproposals on security were not constructive and ignored Russia's key concerns

Says Security proposals were intended as a complete package, not for the US to pick and choose.
Russia doubts Washington is committed to fixing security issues in Europe.
Russia says growing US and NATO military activity is alarming and Russia's red lines are still being ignored.
Ultimatums for Russia to remove troops from parts of its own territory and accompanied by sanctions threats are unacceptable and undermine chances of reaching a deal.
Russia says it will be forced to respond by implementing military technical measures in absence of the US negotiating legally binding security guarantees.
