Blinken said the United States has developed a plan in case of use of nuclear weapons by Russia

“We have it (plan. - 

) ... We are also determined to prevent this conflict from growing,” Blinken said in an interview with CBS.

US national security adviser Jake Sullivan said earlier that Washington had privately warned Moscow of the catastrophic consequences of using nuclear weapons.

Moscow stressed that Russia does not threaten anyone with nuclear weapons.

NATO Secretary General Jens Stoltenberg said that the alliance saw no change in the readiness of Russian nuclear forces.
