Ukrainian President Volodymyr Zelenskyy on Wednesday accused Russia of showing “never before” displayed “ostentatious disrespect” toward the United States, citing a night of strikes on Ukrainian energy infrastructure that left at least 600,000 people without power, despite President Donald Trump’s recent claims of an energy ceasefire between the two countries.

“Russia has never before shown such ostentatious disrespect toward the United States,” Zelenskyy said, according to The Guardian’s live blog, which was being reported by journalist Jakub Krupa on Wednesday.

Zelenskyy described the overnight attack as a deliberate assault on infrastructure that fell under the terms of the ceasefire Trump had announced. “A targeted Russian ballistic missile strike specifically against energy infrastructure – the very infrastructure covered by the ceasefire announced by the American President. The strike was entirely deliberate and demonstrative in its scale,” he said.

The Guardian’s live coverage said at least 600,000 people were left without power Wednesday morning, with temperatures falling below 10 degrees Celsius in Kyiv.

In a separate development, a senior aide to Zelenskyy said Ukraine had been left struggling after Starlink satellite connection speeds were apparently restricted, complicating military operations on the ground. The aide, Serhii Beskrestnov, is widely known by his call sign Flash.

“Our defence forces received no warning about this restriction, and it led to the disruption of a number of missions. Clearly, this action cannot be a coincidence and is linked to the current political situation,” Beskrestnov said.

Zelenskyy was expected in London on Wednesday for talks with UK Prime Minister Andy Burnham, where further remarks from the Ukrainian leader were anticipated, according to The Guardian’s coverage.

NATO Secretary General Mark Rutte was scheduled to visit Estonia on Wednesday morning. In Berlin, German Chancellor Friedrich Merz, described by The Guardian as “embattled,” was set to address the Bundestag with a statement on the EU and Ukraine on Wednesday afternoon.

In a separate item in the same live blog, The Guardian reported that Pope Leo had a “peaceful night” at Rome’s Gemelli hospital after surgery the previous day that confirmed lung adenocarcinoma, which The Guardian’s coverage described as the most common form of lung cancer.

The Guardian’s live blog said further updates would be provided throughout Wednesday. The story was developing.
