KHARKIV, Ukraine — Before the full-scale Russian invasion 14 months ago, Ihor Dudnik lived in a tall, sensible high-rise in this eastern city's biggest neighborhood, Saltivka, once home to at least 400,000 people.
He and his wife, Inna, were close to many of their neighbors and often saw them at a sprawling market that was once one of the largest in Eastern Europe.
