Russian President Vladimir Putin has suspended the Cold War-era Intermediate-range Nuclear Forces Treaty on Saturday after the U.S. said it would withdraw from the arms control pact, accusing Moscow of violations.

Putin said Russia will start work on creating new missiles, including hypersonic ones, and told ministers not to initiate disarmament talks with the Washington, accusing the U.S. of being slow to respond to such moves.

Putin said during a televised meeting with foreign defence ministers, “The American partners have declared that they suspend their participation in the deal, we suspend it as well”
