NATO tells Russia to quit 'nuclear saber rattling,' demands China stop 'lies' amid chemical attack threats

NATO took on two of the world’s superpowers Wednesday and condemned both Russia and China as the 30-member alliance looks to counter the growing threat of a biological, chemical or nuclear attack.

"Russia must stop its nuclear saber-rattling. This is dangerous, and it is irresponsible," NATO Secretary-General Jens Stoltenberg told reporters. 

"Any use of nuclear weapons will fundamentally change the nature of the conflict. And Russia must understand that a nuclear war should never be fought," he continued. "They can never win a nuclear war."

The secretary-general’s comments came just hours after Kremlin spokesman Dmitry Peskov refused to take the threat of a nuclear attack off the table and President Biden warned the use of chemical weapons in Ukraine are a "real threat."
