At least five people have been killed and more than 10 injured in Ukraine in the latest wave of Russian strikes, officials have said.

Emergency services are working at sites hit in Kyiv, Ukrainian President Volodymyr Zelensky said, accusing Russia of targeting civilian infrastructure.

Meanwhile, Moscow’s mayor said about 600 Ukrainian drones were launched towards the city overnight. A warehouse belonging to Russian online retailer Wildberries was hit.

Russia has intensified aerial attacks across Ukraine in recent weeks, while Kyiv has stepped up its targeting of Russian logistics hubs, with the aim of disrupting military supplies.

Air-raid sirens have sounded four times since Saturday night in Kyiv. At least six people, including a child, were reportedly injured, Mayor Vitali Klitschko said.

The mayor of Kryvyi Rih said a 44-year-old man earlier reported missing had been found dead in rubble. Another person was killed and 14 workers of a steel plant were wounded there.

Two people in their 60s were killed when a house was destroyed in Zaporizhzhia.

Zelensky said the cities of Kremenchuk and Kryvyi Rih were hit by ballistic missiles, adding: “Wherever the Russians can reach with their ballistic missiles, they strike civilian infrastructure.”

Russia said its attacks on Kyiv on Saturday night targeted a FirePoint facility producing parts for Ukrainian Flamingo missiles and a factory making components for drones.

The country’s defence ministry also said it hit the Kremenchuk oil refinery in Poltava region, which it said supplied fuel to the Ukrainian military.

Moscow said it struck a steelworks in Kryvyi Rih it said had been making weapons components.

Russia also said it hit a dry cargo vessel near Odesa, claiming it had been carrying military equipment.

Zelensky said 13 regions had come under attack this week, with Russia launching more than 1,550 attack drones, nearly 1,560 guided aerial bombs and 62 missiles.

In Russia, air defences intercepted and destroyed 822 Ukrainian drones, according to its defence ministry.

Three people were injured in an overnight Ukrainian strike, Moscow Mayor Sergei Sobyanin said. He added that roughly a third of the drones Ukraine launched at the capital had been destroyed.

A Wildberries warehouse in Koledino, 25km (15.5 miles) from the centre of Moscow, was hit in the attack, Sobyanin said. Videos shows a fire and a large plume of smoke over the warehouse.
