Forensic experts sifted through the ruins of a dormitory in Russian-held Luhansk after what Russia claims was a Ukrainian drone attack. The death toll stands at 21, many of them young women.
The building's facade was riddled with holes and broken windows. Piles of twisted metal and concrete littered the courtyard.
Russia's Investigative Committee collected evidence. Ukraine's military denied responsibility, stating it struck a drone command unit in compliance with international law.
Russian President Vladimir Putin ordered retaliation. Within 24 hours, Russia launched hundreds of drones and missiles on Kyiv, killing four.
