Kremlin concerned over Trump's decision to leave arms treaty

The Kremlin says it is concerned about U.S. President Donald Trump's decision to withdraw from a landmark nuclear weapons treaty.

Trump announced on Saturday that the United States would walk away from the Intermediate-Range Nuclear Forces Treaty that the U.S. and the Soviet Union signed in 1987 in a major step to ease Cold War tensions.

Dmitry Peskov, spokesman for Russian President Vladimir Putin, told reporters on Monday that Putin is denying Trump's allegations that Russia has violated terms of the treaty. Peskov says the US withdrawal from the treaty would "make the world a more dangerous place."

The Kremlin's comments came as U.S. National Security Adviser John Bolton began his visit to Russia on Monday. Peskov said Russian officials are anxious to hear Bolton's explanations for Trump's decision.
