Russia¡¯s envoy to the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) said Friday that Moscow will revoke its ratification of the pact, a move that Washington denounced as endangering ¡°the global norm¡± against nuclear test blasts.

The announcement by Mikhail Ulyanov added new fuel to tensions between Russia and the United States over Moscow¡¯s invasion of Ukraine and arms control disputes between the world¡¯s largest nuclear powers.

Ulyanov, Moscow¡¯s envoy to the treaty, said on X, the social media platform formerly known as Twitter, that ¡°#Russia plans to revoke ratification (which took place in the year 2000) of the Comprehensive Nuclear-Test-Ban Treaty.¡±
