Ukrainian President Volodymyr Zelenskiy said he doesn't think Vladimir Putin is bluffing when he says Moscow would be ready to use nuclear weapons to defend Russia.
The Russian president said in a televised address last week that Moscow would use "all available means" to protect Russia and its people if its territorial integrity were threatened.
"Look, maybe yesterday it was bluff. Now, it could be a reality," Zelenskiy, who had previously played down such warnings as nuclear blackmail, told CBS News on Sunday.
"I don't think he's bluffing," Zelenskiy added.
The Ukrainian president said Russian strikes on or near two Ukrainian nuclear plants could be considered "contemporary use of nuclear weapons or nuclear blackmail".
