Depriving people of water, electricity and heat as winter begins and the broadening use of so-called suicide drones that nosedive into targets have opened a new phase in Russian President Vladimir Putin’s war.

After a truck bomb explosion a week ago damaged the bridge that links Russia to the annexed Crimean Peninsula, the Kremlin launched what is believed to be its largest coordinated missile attacks in Ukraine since the initial invasion of the country in late February.

Moscow-installed authorities in Ukraine’s occupied southern region of Kherson are urging local residents to evacuate to Russia.

Missile strikes killed at least three people and destroyed an apartment building in the southern city of Mykolaiv, while heavy artillery damaged more than 30 houses, a hospital, a kindergarten and other buildings in Nikopol.
