Russian forces hit a geriatric centre in the Ukrainian city of Sumy and targeted its energy sector in a new wave of airstrikes on Thursday, killing at least one civilian, Ukrainian officials said.

A U.N. monitoring body said attacks on the power grid probably violated humanitarian law, opens new tab while the International Energy Agency said in a report that Ukraine’s electricity supply shortfall in the critical winter months could reach about a third of expected peak demand.

During a daytime strike on the northern city of Sumy, a Russian guided bomb hit a five-storey building, regional and military officials said.

One person was killed and 12 wounded, the interior ministry said on the Telegram messaging app.

President Volodymyr Zelenskiy said rescue teams were checking to see whether people were trapped under rubble.

Images from the site shared alongside the ministry’s post showed elderly patients evacuated from the damaged building lying on the ground on carpets and blankets.

In his nightly video address, Zelenskiy said that Russia had launched 90 guided bomb attacks in the past 24 hours

He also said that Ukraine’s forces had “managed to diminish the occupiers’ assault potential in Donetsk region,” though the situation remained difficult in areas subjected to the heaviest attacks, near the cities of Pokrovsk and Kurakhove.

Russia’s Defence Ministry said its forces had captured the village of Heorhiivka, east of Kurakhove.

The General Staff of Ukraine’s military, in an afternoon report, referred to the village as one of several engulfed by fighting. Popular Ukrainian military blog DeepState said the village was in Russian hands.

Overnight, Ukraine’s air force said it had shot down all 42 drones and one of four missiles launched since Russia invaded Ukraine more than 2-1/2 years ago.

Russian forces have pummelled the energy system in the Sumy region in multiple strikes this week, reducing power in some areas and forcing authorities to use back-up power systems.

Ukraine’s energy ministry said power cuts had been in force in 10 regions due to airstrikes and technological reasons.

In a sign of its concern, the European Union said a fuel power plant was being dismantled in Lithuania to be rebuilt in Ukraine, and that electricity exports would also be increased.

The U.N. Human Rights Monitoring Mission in Ukraine said Russia’s attacks violated international humanitarian law by jeopardizing essential services, including water and heating, while also threatening public health, education and the economy, according to the report.

Kyiv says targeting energy system is a war crime, and the International Criminal Court has issued arrest warrants for four Russian officials and military officers for the bombing of civilian power infrastructure.

Moscow says power infrastructure is a legitimate military target and dismisses the charges as irrelevant.
