Ukraine's Campaign of Strikes Inside Russia and Crimea: What's Happening and Why It Matters

Ukrainian forces killed four people in Russia-annexed Crimea on June 4, 2026, according to Reuters. This was the latest in a series of Ukrainian strikes targeting Russian military infrastructure in occupied territories—a pattern that has intensified over recent months and, according to reports, has claimed civilian lives alongside military targets.

A Pattern of Escalating Attacks

The June 4 incident is part of a larger trend. Between May 1 and 5, 2026, ten people died in Russian-controlled territory, including five from a Ukrainian drone strike in Dzhankoi, Crimea, according to Russia-appointed governor Sergei Aksyonov. On May 5 alone, UN human rights monitors documented 28 people killed and 194 injured in Russian attacks across Ukraine, while attacks in Cheboksary, in Russia's Chuvash Republic, killed at least two and injured 35.

Ukrainian operations have reached far beyond Crimea. According to President Zelensky, forces struck an oil terminal and naval base in Kronstadt, the main hub of Russia's Baltic Fleet, hours before a major economic forum in St. Petersburg. This demonstrated Ukraine's ability to strike strategic military targets deep inside Russian territory.

Earlier strikes have damaged Russian military assets significantly. Explosions in Crimea destroyed nine Russian warplanes, and Ukraine claimed a missile strike on the Crimean headquarters of Russia's navy killed 34 officers, including the fleet commander. A separate missile attack near Simferopol killed two people, according to Crimea's Russian-appointed head of government.

Key Targets: Bridges and Supply Lines

One recurring target has been the Crimea bridge, which Russia's President Putin opened in 2018, four years after annexing Crimea. After a blast killed three people, Putin accused Ukraine of attacking the bridge and called it an act of terrorism. Security camera footage showed a truck from the Russian city of Krasnodar crossing the bridge at the time of the explosion.

Russian authorities later accused Ukraine of attacking the Kerch bridge—a strategic link connecting Russia to Crimea—using unmanned surface vessels (essentially unmanned boats). The same attack killed one person and injured three on a commuter train heading to Kerch. After this incident, Russia halted the Black Sea grain deal, accusing Ukraine of the bridge attack and suggesting potential U.S. and British involvement.

Ukrainian forces have used both aerial and maritime platforms for operations. On January 1, 2026, Russian officials said Ukrainian forces conducted a drone strike in the Kherson Region targeting a café and hotel in Khorly on the Black Sea coast where civilians were celebrating New Year.

How Ukraine Carries Out These Operations—and How Russia Responds

Russian Defense Ministry reports claim Ukraine launches operations from government-controlled territory. The ministry said it had hit unmanned aerial vehicle depots at the Shkolny airfield in Odessa region, alleging that attack drones were launched from there.

Russia has attempted large-scale air defense. The Defense Ministry reported intercepting 53 Ukrainian drones across several regions on a single Wednesday morning in May 2026. Yet Ukrainian strikes have continued, suggesting that Russian air defenses—particularly over supply lines and occupied territories—have gaps.

The human cost has been significant on both sides. Eight people died when a drone struck a passenger bus in Russian-controlled Donetsk, according to Moscow-installed officials, highlighting the difficulty of precise targeting in populated areas.

Why This Campaign Matters

Ukraine appears to be using long-range strikes to impose costs on Russia's occupation of Ukrainian territory and to damage the military infrastructure supporting Russia's broader war effort. By targeting naval bases, airfields, and bridges that connect Russia proper to occupied territories, Ukraine is trying to disrupt Russia's supply lines and command structure. This mirrors tactics used in other prolonged conflicts: during the Iran-Iraq War in the 1980s, both countries systematically attacked each other's oil infrastructure and transportation networks as the war dragged on and expanded beyond the initial territorial dispute.

The broader pattern here reveals something important about how conflicts evolve. What begins as a fight over territory can expand into a campaign against an opponent's economy and military capacity—especially when neither side appears close to victory. The casualty figures underscore this: UN monitors recorded at least 70 killed and more than 500 injured across Ukraine since May 1, with Russian attacks on Ukrainian civilian infrastructure continuing in parallel. Both sides point to the other's actions to justify their own escalation, creating a cycle that deepens the conflict.

Looking forward, Ukraine's ability to sustain these long-range strikes will depend heavily on continued Western military support, particularly for precision munitions and intelligence. Russia, meanwhile, is investing in air defense and conducting retaliatory strikes. Both countries now view cross-border operations as central to their war strategies, suggesting that without serious diplomatic talks, these strikes will likely intensify.

The scope of the conflict—from Russian naval bases in the Baltic Sea to civilian areas in Crimea—shows how far the fighting has spread beyond the original territorial battlelines. The consequences reach well beyond Ukraine and Russia alone.
