WASHINGTON (Reuters) - U.S. President Joe Biden urged Russian President Vladimir Putin to not use tactical nuclear or chemical weapons in the wake of setbacks in Ukraine, in a CBS News interview to air on Sunday.

Ukraine's military drove back Russian forces in a lightning rout in the northeast of the country this week, putting Putin under pressure from nationalists at home to regain the initiative.
