    • Combat operations significantly intensified across all fronts following the expiration of the unilateral Russian ceasefire (00:00 Moscow Time, Apr 21). The Russian MoD officially announced the resumption of its "special military operation."
    • Russia claims strict adherence during the ceasefire but alleges 4,900 Ukrainian violations, including UAV sorties, shelling of border regions, and attempted ground attacks before expiry.
    • Ukraine maintains Russia repeatedly violated its own ceasefire, using the pause for reinforcement, resupply, fortification, and engineering preparations (e.g., confirmed Zherebets River crossings). Ukrainian officials reported nearly 3,000 RU violations in a single day prior.
  • Major Russian Air Attack (Night Apr 20-21 & Morning Apr 21):
    • Composition: A large-scale attack utilizing:
      • 1x Onyx anti-ship cruise missile (from Crimea towards Kherson Oblast).

      • 96x Strike UAVs (Shahed & Imitator types) launched from multiple locations in Russia and occupied Crimea.
    • Ukrainian Air Defense Response:
      • 42 Shahed-type UAVs confirmed intercepted.
      • 47 "Imitator Drones" reported neutralized (likely via EW) or failed to reach targets.
      • 0/3 cruise/anti-radiation missiles intercepted by official Air Force report (though separate field reports indicated a possible Kh-31P downing near Mykolaiv).
