Ukrainian forces push farther into Russia despite Putin's efforts to counter incursion

Ukraine said it blasted its way deeper into the Kursk region of Russia where it has captured dozens of towns and settlements and taken Russians prisoner. It's the largest cross-border attack since Russia invaded and the largest presence of foreign troops in Russia since World War II. Nick Schifrin discussed the incursion with Michael Kofman of the Carnegie Endowment for International Peace.
