articles: Russia seizes Lysychansk
  
  Ukraine’s military said Sunday that it had withdrawn from the key eastern city of Lysychansk, the last city in Luhansk Province still held by Ukraine.
  
  Moscow’s victory means Russian forces are in control of large parts of the Donbas, a coal-rich region that has become Russia’s focal point since its defeat around Kyiv in the spring. Ukrainian forces are now bolstering defenses along the border line between Luhansk and the neighboring province of Donetsk, residents said.
  
  After Ukraine withdrew from Lysychansk, explosions hit the center of a Russian city just north of Ukraine, killing four, officials said. It is the deadliest known episode affecting civilians in Russia since the start of the war. Moscow blamed Ukraine for the attack in Belgorod; Ukraine’s military had no immediate comment.
