Ukrainian President Volodymyr Zelensky has accused Russia of war crimes after air strikes, including on a central square, in the country's second city.
At least 10 people were killed and 35 hurt when the opera house, concert hall and government offices were hit in Freedom Square in Kharkiv.
Speaking to the European Parliament, Mr Zelensky urged the EU to prove it was with Ukraine.
Later the main TV tower in the capital Kyiv was hit, putting media off air.
Footage on social media showed smoke billowing from the steel structure.
Five people died in the attack, Ukrainian officials said, but the tower remains standing.
A nearby memorial to victims of the Holocaust was damaged in the same strike. The Babyn Yar ravine is Europe's largest mass grave of the Holocaust where between 70,000 and 100,000 people, mostly Jews, were shot by the Nazis.
Mr Zelensky said on Twitter that the attack was "history repeating...".
"What is the point of saying 'never again' for 80 years, if the world stays silent when a bomb drops on the same site of Babyn Yar?" he asked.
Meanwhile new satellite images emerged of a huge Russian military convoy which has been outside Kyiv for several days, amid fears of an all-out assault on the capital.
The convoy includes armoured vehicles, tanks, artillery and logistical vehicles, and is said to be less than 18 miles (30km) from the city.
Russia's defence ministry has urged citizens in militarily sensitive areas of Kyiv to leave their homes.
The ministry, quoted by Tass news agency, said the Russian military was not targeting cities, only military infrastructure, and that there was no threat to the civilian population.
