Russia has unleashed a series of ballistic missile strikes across Ukrainian cities, leaving five dead and wounding at least 35, according to officials.

Four fatalities and 19 injuries occurred in the northeastern city of Kharkiv, while one death and 16 injuries were recorded in the capital Kyiv.

Ukrainian President Volodymyr Zelensky called the assault on Kyiv one of the heaviest ballistic barrages on the capital since Russia's full-scale invasion began in 2022.

Ukraine has kept up its own operations against Russian targets. Three oil tankers in the Black Sea were struck, along with sites in the southwestern Stavropol region, Zelensky reported.

Several districts in the Kyiv region suffered hits overnight. Ukrainian forces said air defenses downed 18 of 41 incoming missiles and intercepted 108 drones over the capital.

Kharkiv regional head Oleh Syniehubov reported that a postal terminal on the city outskirts was struck, killing four men aged 24 to 62. Several of the wounded remain in serious condition.

In a Telegram post, Zelensky noted that Russia had deployed roughly 1,450 strike drones, more than 1,640 guided bombs and 99 missiles of various kinds against Ukraine in the past week.

Zelensky also detailed Ukrainian counter-strikes on Telegram.

"SBU units simultaneously struck three oil depots in the Stavropol region, while our Armed Forces hit another fuel facility in the same area," he said.

"Accurate strikes on three Russian shadow-fleet tankers were confirmed in the Black Sea. I thank every unit helping Russia understand that this war must end."

The Caspian Pipeline Consortium, which transports Kazakhstan's oil to Russia's Black Sea port of Novorossiysk, confirmed its terminal was hit.

Two tankers sustained damage, forcing suspension of loading operations. No injuries or spills were reported.

Stavropol's governor said a drone attack sparked a fire at an industrial park.

The Kyiv strikes featured various Russian systems, including Iskander and hypersonic Zircon missiles, plus 125 drones, Ukraine's air force stated.

On Sunday, Kyiv Mayor Vitaliy Klitschko said both homes and commercial buildings were damaged, including a supermarket and dormitory.

Firefighters battled blazes at two warehouses. Ukraine's emergencies ministry reported a logistics hub in Bucha district near Kyiv was hit, injuring two people.

The overnight attacks followed Ukrainian drone strikes that destroyed two warehouses of Russia's largest online retailer, Wildberries, killing eight and triggering major fires.

Seven deaths and 25 injuries occurred at a site in Tambov, roughly 295 miles southeast of Moscow. One death and 37 injuries took place at another Wildberries facility in Elektrostal near the capital.

On Saturday, Zelensky said Ukraine's actions responded to Russian attacks on civilian infrastructure and communities.

Wildberries is widely viewed as Russia's answer to Amazon. The RWB group, merging Wildberries with Russ advertising, was valued at about $12.6bn by Forbes Russia in 2026.

Ukraine has stepped up long-range drone strikes on Russian energy sites, triggering fuel shortages. Earlier this month Kyiv claimed nearly 43 percent of Russia's oil-refining capacity had been disabled.

The BBC has not verified that figure independently.

Ukraine regards Russian oil and gas facilities as valid targets because Moscow depends on fossil-fuel exports to fund its invasion that started in February 2022.

Russia has meanwhile intensified strikes on Ukrainian cities, leading Kyiv to request more ballistic-missile interceptors from European partners.

"Protection against ballistic missiles remains our constant top priority," Zelensky said on Sunday. "Interceptors are needed every day."
