Russia launched a wave of drone and missile attacks across Ukraine on Wednesday night, killing at least three people, Ukrainian officials said.
A 12-year-old boy was among two victims in the capital, said Kyiv Mayor Vitali Klitschko, adding at least 18 people were injured.
One person was also killed in the southeastern city of Dnipro, a Ukrainian official said, while attacks were also reported in other cities across the country.
Across the border, two children, aged five and 14, were killed in a Ukrainian drone attack in Russia's southern Krasnodar Krai region, its governor Veniamin Kondratyev said on Telegram.
The strikes were the latest attacks after a short ceasefire coinciding with Orthdox Easter celebrations at the weekend, during which both sides accused one another of hundreds of violations.
