Russian forces pound Ukraine in increasingly brutal attacks

Russian forces bombarded cities in Ukraine Tuesday as the war raged for a sixth day. Kharkiv, in the northeast, was particularly hard-hit and the port city of Mariupol in the southeast appeared surrounded. Nevertheless, the Pentagon says a drive by Russian forces toward the capital, Kyiv, appears to be stalled as Ukrainian forces kept up their fierce resistance. Nick Schifrin reports from Kyiv.
