Ukraine strikes Russian military plant and oil facilities deep inside Russia; Mariupol port disabled.
Kyiv confirmed long-range missile and drone attacks on Russian industrial and energy sites, while the EU proposed new sanctions targeting Moscow's war economy.
The day on the war
Ukrainian forces conducted significant long-range strikes on June 10, with President Volodymyr Zelenskyy confirming that Ukrainian Flamingo missiles hit a military plant in Cheboksary, Russia, which produces components for drones and missiles. The strikes also targeted oil infrastructure in Russia's Samara and Vladimir Oblasts, extending Kyiv's campaign to impact Russian military and energy capabilities deep behind the front lines.
In addition to these strikes, the Azov Corps reported on June 10 that the Russian-occupied port of Mariupol is no longer operational following Ukrainian attacks. Separately, Ukraine's Center for Countering Disinformation confirmed on June 10 that a Ukrainian drone strike on June 9 destroyed the Chonhar Bridge, a key logistical link connecting Crimea to Russian-occupied Kherson Oblast. These actions underscore Ukraine's continued focus on disrupting Russian supply lines and military-industrial capacity.
