I. Strategic Overview & Information Operations

• Ceasefire Status (Expired 00:00 Moscow Time, Apr 21):

  • The unilaterally declared Russian ceasefire expired with no extension confirmed. Hostilities immediately escalated, primarily via a large-scale Russian air attack.
  • Ukrainian Assessment (President Zelenskyy Report, Apr 20): Documented extensive Russian violations during the declared period (ground assaults, shelling, drone use). Russia did not respond to Ukrainian proposals for a longer, genuine ceasefire.

• Russian Information Operations (IO) / Alleged LOAC Violation:

  • Intensified promotion of allegations regarding a Ukrainian attack on a Russian evacuation group under white flags.
  • Ongoing efforts to portray Ukraine as the primary violator of the ceasefire. Amplification of claims regarding alleged commander misconduct within Russian forces undermining the ceasefire for profit.

  • EU Aid Shift Discussion: Potential European focus shift towards direct investment in Ukraine's domestic defense industry (WP report).
  • UK Production Increase (The Times via TASS): UK plans to significantly increase domestic production of RDX explosives and artillery shells.

      • Zaporizhzhia Oblast -> NW (8 NEW drones launched towards Pavlohrad area).
    • Complexity & Scale: Multiple simultaneous groups, including new launches, moving across large swathes of territory, indicating a sustained and coordinated attack aimed at overwhelming air defenses and striking targets across multiple regions, including the capital.

III. Frontline Developments

• Overall: Intensity remained high leading up to ceasefire expiry. Pokrovsk axis was the area of highest ground assault activity (per Apr 20 reports).

IV. Humanitarian & Ethical Considerations

• Ceasefire Violations & LOAC Concerns:
  • Ceasefire failure led to immediate resumption/escalation of hostilities, notably the large-scale Russian drone attack.
  • Alleged UA Violation (RU IO): Aggressive promotion of claims regarding attack on Russian evacuation group under white flags.
  • Alleged RU Commander Misconduct: Reports amplified alleging Russian commanders undermined the ceasefire for financial gain.
• Civilian Impact:
  • IMMINENT & WIDESPREAD THREAT: Active, large-scale RU strike UAV attack poses immediate threats to civilian populations in Chernihiv, Sumy, Poltava, Kharkiv, Zaporizhzhia, Dnipropetrovsk, Cherkasy, and Kyiv Oblasts. Air raid alerts active, including Kyiv City. Specific, urgent warnings issued for Pavlohrad, Dnipro City, Boryspil, and Zaporizhzhia City.
  • Previous reports of RU shelling/strikes (Orikhiv, Kherson post-ceasefire).
  • Documented difficult conditions in RU-controlled Horlivka due to combat risks.
• POWs & Fallen Soldiers:
  • POW Exchange: Confirmed 246-for-246 exchange occurred.
  • RU source analysis claims increased ratio of bodies returned to Ukraine since Summer 2024. Reports of KIA/WIA evacuations by both sides during the ceasefire period, alongside RU IO alleging UA obstruction.
