A drone strike destroyed a dormitory at the Starobilsk Professional College in Russian-occupied Luhansk on May 21–22, 2026, killing 21 people and wounding 42. Russian officials blamed Ukraine, calling the attack a 'terrorist strike' and presenting images of the rubble and victims at an emergency UN Security Council session. Ukrainian military officials acknowledged carrying out an attack near Starobilsk but stated it targeted a Russian military unit, not a civilian building. Russian President Vladimir Putin condemned the strike, asserting no military facilities were nearby, while hawkish advisors urged broader retaliation, including against European targets. The incident intensified diplomatic tensions and highlighted the growing fog of information in the ongoing war.
