Russian strikes leave 600,000 without power in Ukraine, as Starlink restrictions affect front line
Watch: What we know about Russia's overnight strikes on Ukraine
At least 600,000 people in Ukraine are without electricity after deadly overnight Russian missile and drone strikes, President Volodymyr Zelensky has said.
He said "critical" energy infrastructure had been hit in Kyiv and the capital region and in the north-eastern city of Kharkiv - despite US President Donald Trump's claim on Sunday that an "energy ceasefire" was in place between Russia and Ukraine.
Three people were killed in Kyiv, officials said. Russia said its "massive" strikes had hit communications and energy facilities used by Ukraine's military.
Separately, Zelensky's adviser said speed restrictions on the Starlink communications network had disrupted Ukrainian battlefield "missions".
Serhiy Beskrestnov said Elon Musk's SpaceX company had "implemented overnight a speed limit on Starlink terminals".
He said Ukrainian troops had not been informed about this, and the speed limits - set at 100mph (160km/h) - had already resulted in "the disruption of a number of missions".
"It is clear that this action cannot be a coincidence and is related to the current political situation," Beskrestnov added.
The Starlink system has become a vital tool to give troops in Ukraine internet access
A source in the Ukrainian defence ministry later told the BBC: "Last night, we detected restrictions affecting Starlink connectivity at speeds above 160 km/h, although we are still verifying the exact speed threshold.
