Just after Vladimir Putin launched his invasion of Ukraine, he warned other nations of severe "consequences" should they step in. Just how severe? Some are interpreting his remarks as a veiled, or even not-so-veiled, threat to use nuclear weapons. Coverage:
- The warning: "Whoever tries to interfere with us, and even more so to create threats to our country, to our people, should know that Russia's response will be immediate and will lead you to such consequences as you have never experienced in your history," said Putin, as translated at CNN. "We are ready for any development of events. All necessary decisions in this regard have been made. I hope that I will be heard."
