Intermediate-Range Nuclear Forces Treaty
President Donald Trump's administration says Moscow is in violation of the Cold War-era Intermediate-range Nuclear Forces Treaty (INF).
Secretary of State Mike Pompeo had earlier announced the U.S. would suspend compliance with the INF Treaty with Russia.
The threat comes on the heels of Trump's decision to pull the U.S. from a Cold War-era nuclear deal with Russia.
“The undeniable fact is that this is a gross violation of the [Intermediate-Range Nuclear Force Treaty]” signed in 1987, Russia's foreign ministry said.
