At least two people were killed and three wounded in a Russian drone attack in Ukraine’s Odesa region on Ukraine’s Black Sea coast early on Sunday.

Meanwhile, tens of thousands of residents were left without power after Russia attacked the front-line Zaporizhzhia region overnight into Sunday with drones and missiles.

Regional Governor, Ivan Fedorov, said nearly 60,000 people faced power outages and that two people were wounded in the attacks.

He posted photos on Telegram of buildings reduced to rubble.

As a result of attacks on Ukraine’s power grid, several regions faced rolling power cuts on Sunday, Ukraine’s national energy operator, Ukrenergo, said.

The strikes were the latest in Russia’s sustained campaign on Ukraine’s energy infrastructure as bitter winter temperatures approach.

Ukrainian cities use centralized public infrastructure to run water, sewage and heating systems, and blackouts stop them from working.

Attacks aim to erode Ukrainian morale as well as disrupt weapons manufacturing and other war-related activity almost four years after Russia’s full-scale invasion of its neighbour.
