A 2-year-old girl was killed and 22 people injured, including five children, when a Russian missile struck near the central Ukrainian city of Dnipro, the regional governor said on Sunday.

"Overnight, the body of a girl who had just turned two was pulled from under the rubble of a house," Serhiy Lysak wrote on the Telegram messaging channel.

Seventeen people were being treated in hospital after the attack on a residential area by Iskander short-range cruise missiles, Lysak said.

Reuters could not independently verify the report. There was no immediate reaction from Moscow.

Mykola Lukashuk, head of the Dnipropetrovsk region council, said 17 children have died in the region since Russia launched its full-scale invasion of Ukraine in February 2022.

"No words can soothe the pain of parents who have lost the most precious thing in their lives," Lukashuk said.

The war has killed at least 485 children in Ukraine and injured nearly 1,500, the country's Office of the Prosecutor General said on Sunday on Telegram.

The missile hit between two two-storey residential buildings in the Pidhorodnenska community, partially destroying them and damaging a number of houses, cars and infrastructure, Lysak said.

"Once again, Russia proves it is a terrorist state," Ukraine's President Volodymyr Zelenskiy wrote on Saturday after the first reports of the explosions.

Moscow and Kyiv deny their military forces target civilians.

Pictures posted on social media showed rescue teams working at a shattered, smouldering building amid piles of twisted building materials.

Following the attack in Dnipro, Russia launched a new wave of overnight air strikes on the country. Ukraine's air force said on Sunday it destroyed more than half of the air targets.

Four of the six cruise missiles and three of the five Iranian-made Shahed drones launched by Russia were downed, the air force said on Telegram.

Kyiv's city military administration earlier said all Russia-launched targets approaching the capital had been intercepted. It was not immediately clear where the missiles and drones that were not destroyed hit.

Russia has repeatedly attacked Ukraine's capital since May, chiefly at night, ahead of a long-expected Ukrainian counteroffensive to reclaim territory, in what Ukrainian officials say is an attempt to inflict psychological distress on civilians.
