Russia attacks Ukraine; conflict reverberates around globe

Russia launched a wide-ranging attack on Ukraine on Thursday, hitting cities and bases with airstrikes or shelling, as civilians piled into trains and cars to flee. Ukraine’s government said Russian tanks and troops rolled across the border in what it called a “full-scale war” that could rewrite the geopolitical order and whose fallout already reverberated around the globe.

In announcing a major military operation, Russian President Vladimir Putin deflected global condemnation and cascading new sanctions — and chillingly referred to his country’s nuclear arsenal as he threatened any foreign country attempting to interfere with “consequences you have never seen.”

NATO’s chief said the “brutal act of war” shattered peace on the European continent, as the U.S.-led alliance mobilized more troops to move toward eastern Europe.
