KYIV, Ukraine—Street fighting broke out in Ukraine’s second-largest city and Russian troops squeezed strategic ports in the country’s south Sunday, advances that appeared to mark a new phase of Russia’s invasion following a wave of attacks on airfields and fuel facilities elsewhere in the country.
Following its gains on the ground, Russia sent a delegation to Belarus for peace talks with Ukraine, according to the Kremlin. Ukraine’s president suggested other locations, saying his country was unwilling to meet in Belarus because it served as a staging ground for the invasion.
