Russia steps up Ukraine offensive as Biden increases economic pressure

 Russia expanded its military offensive in Ukraine Friday, hitting targets further west from the air as its ground forces maneuvered to encircle the capital, Kyiv, and pressure besieged cities across the country like Mariupol.

Moscow’s troops have struggled to make progress against fierce resistance in more than two weeks of war. But their assault has left civilians trapped and bombarded in worsening conditions, creating a humanitarian crisis that has horrified much of the world.

President Joe Biden was set to call for an end to normal trade relations with Moscow, a senior administration official familiar with the matter told NBC News, a move that would allow the West to raise tariffs on Russian products as it seeks to isolate and punish Moscow for the invasion of its democratic neighbor.
