What happened in Ukraine today? Latest updates here

Ukraine's government pleaded for help as civilians piled into trains and cars to flee.

President Vladimir Putin ignored global condemnation and cascading new sanctions as he unleashed the largest ground war in Europe in decades, and chillingly referred to his country's nuclear arsenal. He threatened any country trying to interfere with "consequences you have never seen."
