MOSCOW — The Russian Foreign Ministry says it has received official notification from the United States that it intends to walk out of a key Cold War-era treaty.

U.S. Secretary of State Mike Pompeo announced at a NATO meeting Tuesday that Washington would suspend its obligations under the 1987 Intermediate-Range Nuclear Forces Treaty (INF) in 60 days due to Russia's alleged "cheating."

Russia has denied U.S. and NATO allegations that it is violating the landmark treaty that banned an entire class of weapons.

Foreign Ministry spokeswoman Maria Zakharova told reporters on Wednesday that Moscow has been received an official notice from Washington that quotes unspecified evidence of Russian violations. Zakharova insisted that Russia has always respected the treaty and considers it "one of the key pillars of strategic stability and international security."
