Overview
- Russian authorities say a drone strike hit a lycée dormitory in occupied Starobilsk in the night of May 21–22, with casualty tallies rising as rescue teams continued clearing rubble.
- Ukraine denies striking civilians and says its forces targeted nearby Russian military sites, including elements of the Rubikon drone unit stationed in the Starobilsk area.
- Moscow called the Starobilsk hit a “monstrous crime,” convened an emergency UN Security Council meeting and vowed military reprisals for the attack.
- Hours after warnings of a large Russian response, Russian forces carried out massive overnight strikes on Kyiv in the night of May 23–24, and the Russian Defence Ministry confirmed use of Orechnik and other long‑range weapons, with multiple deaths, dozens injured and extensive damage reported.
- The confirmed use of Orechnik, a hypersonic intermediate‑range missile that can carry conventional or nuclear warheads, raises political and strategic stakes, complicates independent verification in occupied areas and increases the risk of wider escalation and diplomatic fallout.
