The White House says President Biden will head to Alabama next week to visit a Lockheed Martin factory that produces Javelin anti-tank missiles — one of dozens of weapons systems which the U.S. has been supplying to Ukraine. The announcement came as Russian President Vladimir Putin warned Western nations against intervening in the war.

President Vladimir Putin: “If someone decides to intervene in the current events in Ukraine from the outside and create unacceptable strategic threats for Russia, then they must know that our response, our retaliatory strikes, will be lightning fast, quick. We have all the tools for this, such that no one else can boast of right now. And we won’t brag. We will use them if needed. And everyone should know about it. We have made all the decisions on this matter.”
