Seven people, including three children, have been killed in the western Ukrainian city of Lviv in a new wave of Russian attacks, the mayor said.
The strike came as Ukraine continues to grapple with the deaths of at least 50 people at a military facility in the central city of Poltava on Tuesday.
Lviv Mayor Andriy Sadovy said Russia had attacked the city early Wednesday morning with drones and hypersonic missiles. The dead included a baby, a 14-year-old girl and a woman who worked as a midwife in the city, officials said.
Explosions were also heard over the capital Kiev as air defenses targeted Russian missiles. Meanwhile, five people were reportedly injured after flats in the city of Kryvyi Rih were hit.
The Ukrainian military reported that the entire country has been placed on air raid alert.
According to Mr Sadovy, several residential buildings are on fire and two schools remain closed on Wednesday due to the attacks.
Rescue workers continue to search through the rubble of a military facility in Poltava for survivors of Tuesday’s attack.
According to the Ukrainian Defense Ministry, people did not have enough time to reach the shelters after the air raid siren went off.
President Volodymyr Zelensky promised that what he called “Russian scum” would pay for the attack and repeatedly called for more air defenses so that Ukraine could protect itself by launching long-range missile attacks of its own.
Western Lviv has been largely spared the worst fighting during the two-and-a-half-year war, but Russian attacks last week targeted energy infrastructure, causing disruptions, officials said.
Moscow has not commented on the latest attack.
Mr Zelensky will meet the Irish prime minister on Wednesday as Ireland prepares to announce new funding for Ukraine’s war effort.
The Taoiseach will also announce €43 million (£36 million) in aid to Ukraine, of which €3 million (£30 million) will be allocated to partner organisations through development agency Irish Aid.
The Irish government said the package will provide essential humanitarian assistance, support rehabilitation and eventual reconstruction, and contribute to Ukraine’s longer-term goals.
