A senior Russian diplomat said that Moscow would no longer inform the US about its missile tests, an announcement that came as the Russian military deployed mobile launchers in Siberia in a show of the country’s nuclear capability amid the fighting in Ukraine.

Russian deputy foreign minister Sergei Ryabkov said in remarks carried by Russian news agencies that Moscow had halted all information exchanges with Washington after previously suspending its participation in the last remaining nuclear arms pact with the US.
