I. Strategic Overview & Information Operations

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

  • The unilaterally declared Russian ceasefire expired with no extension confirmed.
  • Ukrainian Assessment (President Zelenskyy Report, Apr 20): Documented extensive Russian violations during the declared period, including ground assaults (highest on Pokrovsk axis), assaults on the Kursk axis, widespread shelling, and significant FPV drone use. Russia did not respond to Ukrainian proposals for a longer, genuine ceasefire.
  • Ukrainian Stance (Zelenskyy): Maintain "mirror-like" response to Russian actions.
  • Russian Claims: Continued claims of widespread Ukrainian violations post-ceasefire commencement.
  • POW Exchange: A 246-for-246 exchange occurred during the ceasefire period.

• 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.
  • Continued dissemination of narratives regarding difficult conditions in occupied areas (e.g., Horlivka).
  • NEW IO: Promotion of narratives linking Orthodox faith revival in Russia to the war effort and national resilience (RVvoenkor via Operatsiya Z).

• Geopolitical Developments:

  • US ZNPP Proposal (WSJ via TASS): Reports suggest a US proposal for neutral status for territories around ZNPP, potentially transferring control to Washington.
  • Trump Statements: Ongoing commentary on Donald Trump's statements regarding a potential Russia-Ukraine agreement; NEW: Trump comments on requests for US tariff reductions (TASS).
  • 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.

II. Air, Missile, Drone Warfare & Logistics Impact

• Post-Ceasefire Russian Air Activity (MASSIVE ESCALATION - Ongoing as of 01:11 UTC):

  • Strike UAV Threat (Significant & Widespread): A large-scale, multi-vector Shahed-type drone attack is currently underway across Ukraine.
    • Affected Oblasts (Threats/Active Drones): Chernihiv, Sumy, Poltava, Kharkiv, Dnipropetrovsk, Zaporizhzhia, Kyiv.
    • Specific City Warnings: Pavlohrad (Dnipropetrovsk Oblast) remains under threat from multiple drones; Kharkiv City targeted by drones from north and potentially Chuhuiv area (3 drones confirmed targeting Kharkiv - Nikolaevskiy Vanyok, 00:45 UTC). Potential for loud impacts noted.
    • Drone Group Vectors & Numbers (UA AF 01:00 UTC & Nikolaevskiy Vanyok 00:56 UTC):
      • Eastern Chernihiv Oblast -> SW (towards Kyiv/Poltava). (~6 drones heading towards/through Pryluky - Vanyok)
      • Sumy Oblast -> SW (towards Poltava Oblast). (~13 drones moving from Sumy towards Poltava - Vanyok)
      • Kharkiv Oblast -> S/SW (towards Poltava/Dnipropetrovsk Oblasts). (~6 drones towards/through Krasnohrad; ~4 near Lozova; ~2 past Kharkiv towards Chuhuiv - Vanyok)
      • Dnipropetrovsk Oblast -> South of Pavlohrad, arbitrary course. (~14 drones active near Pavlohrad/Ternivka, high risk - Vanyok)
      • NEW Groups: Zaporizhzhia Oblast -> NW (towards Dnipropetrovsk Oblast).
    • Complexity: Multiple simultaneous groups moving across large swathes of territory, indicating a coordinated attack aimed at overwhelming air defenses and striking targets across multiple regions.
  • Reconnaissance UAVs: Previously detected over Sumy and Chernihiv Oblasts.
  • Air Alerts: Active across Zaporizhzhia Oblast and warnings active for multiple central, eastern, and northern oblasts due to UAVs.
  • Tactical Aviation: Previously active, launching KABs towards Sumy, eastern Kharkiv, and Donetsk Oblasts.
  • Reported Impacts (Earlier): Incoming strikes ("prilety") reported in Kharkiv and Sumy Oblasts; UA AD activity over Donetsk. RU MLRS on Orikhiv; artillery on Kherson city.

• Previous Air/Drone Activity:

  • RU Claim (Pre-Ceasefire, Colonelcassad): Video released claiming successful strikes by 16th Spetsnaz Bde (coordinated with D-30 artillery, 120mm mortar) destroying UA dugout, ammo, personnel in Serebryanske forestry (Lyman axis). Note: Claimed as pre-ceasefire footage.
  • RU Claim: Alleged UA heavy bomber drone use near Chasiv Yar during ceasefire.
  • UA Actions (Recent): Confirmed destruction of Russian BM-21 Grad MLRS; FPV strikes; precision strike video released.

• Logistics & Capabilities:

  • Potential EU Aid Shift: Focus potentially moving towards investment in Ukrainian domestic production.
  • UK Production Boost: Plans to increase RDX/artillery shell manufacturing.
  • China: Previous demonstration of quadrupedal combat robot.

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). Russian assaults reported ongoing on the Kursk axis during the declared ceasefire. No major ground offensive shifts reported immediately following ceasefire expiry, focus appears to be on the large-scale air attack.
• Donetsk Axis: Previously subject to renewed KAB strikes post-ceasefire.
• Lyman Axis (Serebryanske Forestry): RU sources released video (claimed pre-ceasefire) showing coordinated Spetsnaz/Artillery strikes destroying UA positions/ammo in this area.
• Chasiv Yar / Kramatorsk Axis: RU sources claimed Ukrainian heavy drones active near Chasiv Yar during ceasefire.
• Orikhiv Axis (Zaporizhzhia): Previously subjected to Russian MLRS attack. Subject to ongoing RU strike UAV threat. RU claimed UA body evacuations near Robotyne during ceasefire.
• Kherson Axis: Kherson city previously targeted by Russian artillery.

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 THREAT: Active, large-scale RU strike UAV attack poses immediate, widespread threats to civilian populations in Chernihiv, Sumy, Poltava, Kharkiv, Zaporizhzhia, Dnipropetrovsk, and Kyiv Oblasts. Air raid alerts active. Specific warnings issued for Pavlohrad and Kharkiv 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.
