Russia and Ukraine have intensified long-range drone and missile attacks targeting strategic infrastructure and residential areas this week.

The escalation signals a shift toward deeper strikes behind enemy lines, potentially expanding the geographic scope of the conflict and increasing civilian casualties.

Russia's defence ministry said it shot down between 389 [1] and 419 [2] Ukrainian drones. The attacks targeted various regions, including Moscow and the Leningrad region. Ukrainian forces also struck the port city of Kronstadt, which is located more than 850 km [1] from the Ukrainian border.

Simultaneously, Russian forces targeted the city of Sumy in Ukraine. Reports indicate that six guided bombs [1] hit a residential area in the city. These strikes killed at least five people [1] and injured more than 40 [1].

President Volodymyr Zelenskyy and other Ukrainian officials said the strikes on Russian energy sites and the port of Kronstadt are part of a broader effort to degrade Russian military capabilities. Russia said it is targeting Ukrainian infrastructure to weaken the war effort.

Both nations have increased the use of unmanned aerial vehicles to bypass traditional air defenses. The strikes in the Leningrad region and St Petersburg demonstrate Ukraine's ability to reach high-value targets far from the front lines, a development that forces Russia to redeploy air defense assets away from the combat zones.

Russia's defence ministry said it shot down between 389 and 419 Ukrainian drones.

The ability of Ukraine to strike targets like Kronstadt, deep within Russian territory, indicates an evolution in their long-range strike capabilities. By targeting energy sites and naval ports, Ukraine is attempting to disrupt Russian logistics and economic stability. Conversely, Russia's continued use of guided bombs on residential areas in Sumy underscores a strategy of attrition and psychological pressure on Ukrainian civilian populations.
