Russian President Vladimir Putin warned Wednesday that if any other country intervenes in Russia's military operation in Ukraine, Moscow will launch a quick-fire military response. Speaking to lawmakers, Putin said that "if anyone sets out to intervene in the current events from the outside and creates unacceptable threats for us that are strategic in nature, they should know that our response... will be lightning-fast".

Putin said that the military would not hesitate to use the most modern weaponry. "We have all the tools for this, that no one else can boast of having. We won't boast about it: we'll use them, if needed."
