Ukraine War 2026

ACTIVE WAR CRITICAL UPDATED APRIL 2026 10/10

Russia's full-scale invasion of Ukraine, launched on February 24, 2022, continues into 2026 as the world's deadliest armed conflict. ACLED records approximately 78,000 people killed in Ukraine in 2025 alone — the highest of any conflict globally. Fighting continues along a front stretching across eastern and southern Ukraine, with Russian forces maintaining control of significant portions of Donetsk, Luhansk, Zaporizhzhia and Kherson oblasts, as well as Crimea. Ceasefire negotiations have so far yielded no lasting agreement.

Background

Russia launched its full-scale invasion of Ukraine on February 24, 2022, following years of lower-intensity conflict in the Donbas region that began after Russia's annexation of Crimea in 2014. The invasion was framed by Moscow as a "special military operation" but has been widely condemned as an act of aggression by the international community, the UN General Assembly, and the International Criminal Court, which issued an arrest warrant for President Vladimir Putin in March 2023.

Ukraine's initial resistance defied most military predictions. By 2025/26, the front has largely stabilized along eastern and southern lines, though fighting remains intense. Russia controls approximately 18% of Ukrainian territory. Drone and missile strikes on Ukrainian civilian infrastructure have increased dramatically — ACLED records a 30% increase in strikes causing civilian casualties in 2025.

Current Situation (April 2026)

The war enters its fifth year with no end in sight. An Easter ceasefire announced April 10–12, 2026 was violated 2,299 times — including 747 attack drone strikes and 1,045 FPV drone strikes — within 48 hours of taking effect (Ukraine Armed Forces). Russia claimed full control of Luhansk oblast in early April, though only 0.2% of the oblast's pre-war population remains in Russian-controlled areas.

Russia captured roughly 1,897 sq mi over the past 12 months, but territorial momentum has slowed sharply — only 17 sq mi changed hands in the four weeks from March 10 to April 7 (Russia Matters War Report Card). Ukrainian forces have retaken 480 sq km in southern regions since January and ~180 sq km around Kupyansk in late 2025. Ukrainian long-range drone strikes have reduced Russia's oil export capacity by an estimated 40%.

Casualty estimates as of early 2026: Russia approximately 1,000,000 military casualties (killed and wounded); Ukraine 250,000–300,000. Formal peace talks have not resumed. European nations continue to increase defense spending in response to the conflict.

Regional Hotspots

Key Actors

Russian Federation

Aggressor state. Estimated 200,000–285,000 military dead. Prosecuting a war of attrition using artillery, drone swarms, and guided missiles. Deploying North Korean troops (estimated 10,000+) as supplementary infantry. Economy on full war footing, with significant help from sanctions evasion through third countries.

Ukraine

Defending state. Receiving military and financial support from NATO allies, though the scale and continuity of US support remains uncertain under the Trump administration. Has developed significant domestic drone manufacturing capacity. Fighting continues to be sustained at enormous human cost.

External Actors

North Korea supplies ammunition and troops. Iran has provided drones. The US, EU, and UK provide weapons and financial aid to Ukraine. The conflict has become a proxy arena for a broader contest between NATO-aligned states and Russia's partners.

Humanitarian Impact

Over 6 million Ukrainians remain as refugees in Europe (UNHCR). Millions more are internally displaced. Russian strikes have systematically targeted Ukraine's power grid, water infrastructure, and heating systems — a deliberate strategy to make civilian life untenable during winters. The UN has documented executions, torture of prisoners, and forced deportations of Ukrainian children to Russia.
