Ukraine energy supply under Russian attacks, heavy fighting in east

As the winter's first snow fell in Kyiv, authorities said they were working to restore power nationwide after Russia earlier this week unleashed what Ukraine said was the heaviest bombardment of civilian infrastructure of the war, which began in late February when Russia invaded its neighbour.

About 10 million people were without power, President Volodymyr Zelenskiy said in a Thursday evening video address. Authorities in some places ordered forced emergency blackouts, he said.

Ukraine typically experiences long, cold winters with mean temperatures several degrees below zero Celsius and lows down to -20 Celsius. A UN agency said a serious humanitarian crisis loomed, with millions facing "constant power cuts" this winter.

Meanwhile, a Dutch court convicted two Russian men and a Ukrainian man in absentia of murder for their role in the shooting down of Malaysian Airlines Flight MH17 over eastern Ukraine in 2014. Russian-backed forces and the Ukraine military have been fighting in eastern provinces since 2014, the same year Russia annexed Crimea from Ukraine.

"Punishment for all Russian atrocities - both present and past - will be unavoidable," Zelenskyy wrote on Twitter in response to the court's decision.

Moscow called the ruling "scandalous".

The Donetsk region has experienced the heaviest fighting in Russia's nine-month-long war on Ukraine. Russian forces were reinforced by troops pulled from Kherson city in the south which Ukraine recaptured last week. Russian forces fired artillery on the towns of Bakhmut and nearby Soledar, among others, the Ukrainian military said.

Russian fire also hit Balakliya in northeastern Kharkiv region, which Ukraine recaptured in September, and Nikopol, a city on the opposite bank of the Kakhovka reservoir from the Zaporizhzhia nuclear power station, the statement said.

The board of the UN nuclear watchdog, the International Atomic Energy Agency (IAEA), again called on Russia to end all actions at Ukrainian nuclear power plants and immediately withdraw from Zaporizhzhia, Europe's largest nuclear power plant.

A deal brokered by the United Nations and Turkey in July aimed at easing global food shortages by helping Ukraine export its agricultural products from Black Sea ports, was extended for four months on Thursday, though Russia said its own demands were yet to be fully addressed.

Ukraine's Zelenskiy said that since Aug 1, more than 450 ships had carried 11 million tonnes of Ukrainian grain and other foodstuffs around the world.

"Tens of millions of people, primarily in African countries, have been saved from starvation ... food prices are significantly lower than they would be without our food exports," Zelenskiy said in his video address.

The retreat by Russian forces from the strategic southern city of Kherson last week following a Ukrainian counter-offensive was celebrated by its people, but also created uncertainty.

The central square on Thursday was a frenetic melee of humanitarian aid queues and displays of patriotism.

At one end, a man played the Ukrainian anthem on the accordion as bystanders sang along; a man strummed out popular Ukrainian rock songs on the other. Children and teenagers asked a soldier to sign flags draped around their shoulders.

People queued to swap Russian SIM cards in their mobile phones for Ukrainian ones and hundreds waited for humanitarian aid, but said they had no idea what they might receive.

"We're fine, but we don't know what to expect. Nothing is over yet. On that bank of the river, the forces are gathering. On this side, they are gathering. We are in the middle," said Ihor, 48, an unemployed builder.

Ukrainian and Russian gunners on Thursday traded shellfire across the Dnipro River that bisects the Kherson region, the thumps echoing as a freezing rain drenched the city.

Investigators in recaptured territory in the area uncovered 63 bodies bearing signs of torture after Russian forces left Ukraine's interior minister was quoted as saying.

Russia denies its troops target civilians or have committed atrocities. Mass burial sites have been found in other parts previously occupied by Russian troops, including some with civilian bodies showing signs of torture.
