A children's hospital in Kyiv has been hit by missiles as Russia unleashed a deadly barrage across Ukraine.
The attack is the biggest bombardment of the Ukrainian capital for several months, officials said.
At least 20 people have been killed and around 50 others injured, according to the country's interior ministry.
The daylight attacks included Kinzhal hypersonic missiles, one of the most advanced Russian weapons, the Ukrainian air force said.
The Kinzhal flies at 10 times the speed of sound, making it hard to intercept.
City buildings shook from the blasts.
Ukrainian President Volodymyr Zelenskyy said Russia had targeted five cities with more than 40 missiles of different types.
The attack struck Okhmatdyt children's hospital in Kyiv - Ukraine's biggest children's medical facility.
The mayor of the Ukrainian capital, Vitali Klitschko, confirmed that the hospital had been hit but did not say whether there were any casualties.
In a post on social media, Zelenskyy's chief of staff Andriy Yermak also accused Russia of "deliberately targeting" children.
