The United States delivered Russia a 60-day ultimatum on Tuesday to come clean about what Washington says is a violation of a arms control treaty that keeps missiles out of Europe, saying only Moscow could save the pact, Reuters reported.

Pompeo said that Russia’s actions “greatly undermine America’s national security and that of our allies”.
He also said that the United States had evidence that the test launches were from a single site in Russia, the Soviet-era base Kupustin Yar, near Volgograd, southeast of Moscow.

“In the light of these facts, the United States declares Russia in material breach of the treaty and will suspend our obligations ... effective in 60 days unless Russia returns to full and verifiable compliance,” Pompeo said.
