War in Donbas / Russo-Ukrainian War (2014–present; full-scale invasion 2022–present)
Status: ongoing high-intensity interstate war, as of the September 2026 observation window.
Overview
- Belligerents: Ukraine (Armed Forces of Ukraine, National Guard, Territorial Defense) with Western military/financial support (US, EU, UK and others). Versus: Russian Federation (Armed Forces, Wagner/irregular formations earlier in the war) and, in the 2014–2022 phase, the self-declared Donetsk and Luhansk People's Republics (DPR/LPR) backed by Russia. North Korean troops were reported fighting alongside Russia from late 2024 (Western/Ukrainian/South Korean intelligence claims — attributed).
- Dates: War in Donbas from 2014 (Crimea annexation March 2014; Donbas fighting from April 2014); full-scale Russian invasion 24 February 2022. Ongoing — in its fifth year as of September 2026.
- Theater: Eastern and southern Ukraine (Donetsk, Luhansk, Kharkiv, Zaporizhzhia, Kherson oblasts), nationwide missile/drone strikes on Ukrainian cities and energy infrastructure, cross-border strikes into Russia, Black Sea.
Causes (attributed)
- Ukraine and Western governments describe the war as an unprovoked Russian war of aggression aimed at subjugating Ukraine and reversing its Western orientation; Russia's stated justifications (protection of Russian-speakers, "demilitarization/denazification," NATO expansion concerns) are presented by Moscow and rejected by Kyiv and Western capitals as pretexts. This dossier takes no position: both characterizations are attributed claims.
- Analysts widely trace the 2014 phase to the Euromaidan revolution, the flight of Viktor Yanukovych, Russia's annexation of Crimea, and Russian-backed separatism in Donbas; the 2022 escalation followed Russia's recognition of the DPR/LPR and massed invasion.
- UN General Assembly resolutions have condemned the invasion (attributed to UN voting records); Russia disputes their legitimacy.
Course
After 2014, the Minsk agreements (2014–2015) froze but did not end Donbas fighting (~13,000+ killed 2014–2021 per UN OHCHR estimates widely cited before 2022 — see casualties). On 24 February 2022 Russia launched a full-scale invasion; Kyiv held, Russia withdrew from the north, and the war settled into grinding attrition in the east and south, with Ukrainian counteroffensives in 2022 (Kharkiv, Kherson) and 2023, and renewed Russian offensives from late 2023. Both sides escalated long-range strikes: Russia systematically targeting Ukrainian energy infrastructure; Ukraine striking Russian refineries, depots and military sites. UN reporting documents sharply rising civilian harm in 2025–2026, with short-range drones described by HRMMU as "hunting" frontline civilians.
Casualties (attributed; military figures heavily contested — none presented as fact)
- Civilians (verified): 16,874 killed and 51,273 injured since 24 February 2022 (through July 2026) — UN OHCHR/HRMMU via ukraine.un.org, updated July 2026; the UN stresses actual figures are likely higher. July 2026: 437 killed, 2,610 injured — highest monthly toll since March 2022; first seven months of 2026: 1,830 killed, 10,638 injured, up 44% year-on-year (UN News, August 2026). February 2026 fact sheet: 15,172 killed, 41,378 injured (four-year mark).
- Russia's own report: Russian authorities reported 250 civilians killed and 1,596 injured inside Russia in H1 2026 — UN not in a position to verify (Reuters, July 2026).
- Donbas 2014–2021: ~13,000+ total killed — UN/OHCHR pre-invasion estimate widely cited (including ~3,000+ civilians); methodology details not re-verified in this pass — treat as attributed estimate.
- Military deaths: both sides' claims are contested and no verified total exists — UNVERIFIED. Western intelligence/media estimates cited in press (hundreds of thousands of casualties on each side including wounded) vary widely and are not verified.
- Displaced: millions (UNHCR; exact September 2026 figure UNVERIFIED in this pass).
Current status (as of September 2026)
- Full-scale war in its fifth year; no diplomatic solution in sight (UN News, August 2026). Civilian casualties rising: 2025 and 2026 each worse than 2023–2024 (OHCHR February 2026 fact sheet).
- Front lines concentrated in Donetsk/Zaporizhzhia; both sides conducting deep strikes. US-led talks reported as stalled (press reporting, mid-2026).
- Trackers: UCDP codes it as an active interstate war (detail not directly retrieved — per plan's adaptation note, treat as active); ACLED tracks events; IISS Armed Conflict Database covers it as a major interstate conflict.
Tracker pulse
- UN OHCHR/HRMMU: the gold standard for verified civilian casualties; monthly protection-of-civilians updates.
- ACLED: event-level data on battles, strikes, and civilian targeting.
- UCDP: active interstate conflict coding (not directly retrieved in this pass).
- Debate: military casualty figures are the most contested numbers in the war; both governments' figures are treated by independent analysts as unreliable. Allegations of war crimes (Bucha, Mariupol, deportation of children, strikes on energy infrastructure) are documented by the UN/ICC and denied or disputed by Russia — attributed at all times.
Validation tier
Tier 1 — 2+ independent trackers (UN OHCHR verified civilian data + ACLED event data + UCDP active-conflict coding) with massive convergent evidence; military death tolls explicitly excluded from validation (UNVERIFIED).
UNVERIFIED points
- Military deaths on both sides (all figures contested; none adopted).
- Precise territorial control at the September 2026 window.
- North Korean troop involvement scale and casualties (intelligence claims, attributed).
- Pre-2022 Donbas toll methodology (~13,000 figure not re-verified in this pass).
- Exact displacement totals as of September 2026.
