In his nightly address on Monday, Ukrainian President Volodymyr Zelenskyy stated that this Russian strike was as vile as previous ones, targeting critical civilian infrastructure.

He stated that Ukraine's energy sector had sustained significant harm, but promised that wherever there was a power outage, restoration efforts were already underway. Our repair teams would work tirelessly to restore electricity. In all cities and communities that required it, the Points of Invincibility were set to open now.

On Monday, Russia's Ministry of Defense announced that its long-range precision and sea-based weapons were deployed against critical energy infrastructure facilities that supported Ukraine's military-industrial complex, and all designated targets were hit.

Biden condemned Russia's "outrageous attack" on Monday and its targeting of critical Ukrainian energy sites, which he has supported since the full-fledged invasion in February 2022.

The White House leader strongly condemns Russia's ongoing war against Ukraine and its attempts to push the Ukrainian people into darkness.

On Monday, the American nonprofit Institute for the Study of War classified Moscow's offensive as one of the largest combined drone and missile attacks on Ukrainian critical infrastructure.

Recently, Russia and Ukraine have intensified their aerial attacks, with Kyiv launching a massive drone assault on Moscow, which is not a common direct target in the war, according to Russian officials.

In the past few weeks, Ukraine has been conducting a secretive military operation in Russian territory, with a focus on the Kursk region, where a nuclear power plant is located. On Tuesday, the International Atomic Energy Agency's Rafael Grossi will visit the site to assess local safety and security.
