At least seven people, including three children, have been killed overnight after a Russian drone hit a petrol station in the north-eastern city of Kharkiv.
The strike caused a massive fire that burned down 15 private houses, while 50 people were evacuated as emergency workers tackled the blaze.
It comes as Ukrainian President Volodymyr Zelensky sacked army chief Valeriy Zaluzhny and replaced him with Oleksandr Syrsky.
It follows days of speculation that Zelensky was considering dismissing Zaluzhny, who is seen by many Ukrainians as a national hero for overseeing the war effort since February 2022.
“We discussed what renewal the Armed Forces of Ukraine need. We also discussed who could be in the renewed leadership of the Armed Forces of Ukraine. The time for this renewal is now,” Zelensky’s statement said on Telegram.
In other developments, Ukrainian troops have shot down a Russian attack helicopter in eastern Ukraine near the city of Avdiivka as soldiers step up street fighting, Kyiv claimed.
Meanwhile, Russian forces launched the second largest combined drone and missile strike on Ukraine this year with around 64 munitions hitting the country, according to a US think tank.
