US condemns announcement by Mikhail Ulyanov, saying it ‘needlessly endangers the global norm’ against nuclear testing

A senior Russian diplomat has said that Moscow will revoke its ratification of the Comprehensive Nuclear Test Ban Treaty (CTBT), in a move Washington denounced as jeopardising the “global norm” against nuclear test blasts.

Mikhail Ulyanov, the Russian representative to the international nuclear agencies in Vienna, was speaking after Vladimir Putin suggested Moscow might resuming testing for the first time in 33 years, signalling another downward turn in relations between the world’s two biggest nuclear powers

Russian president uses speech to highlight new missile capabilities and says he may abandon test ban treaty

Vladimir Putin has ramped up his nuclear rhetoric, saying his country had successfully tested the nuclear-powered, nuclear-capable Burevestnik strategic cruise missile, as he suggested Russia could resume nuclear testing for the first time in more than three decades.

The Russian president said in a speech on Thursday at the annual Valdai Discussion Club in the Black Sea resort of Sochi that Russia had also almost completed work on its nuclear-capable Sarmat intercontinental ballistic missile system, which is capable of carrying at least 10 nuclear warheads on each missile.

“In the event of an attack on Russia, no one has any chance of survival,” he said, adding that he was “not sure if we need to carry out nuclear tests or not”.
