A fourth person was killed in the ‌Belgorod region bordering northeastern Ukraine, local authorities said, while Russia’s defense ministry said by midday more than 1,000 Ukrainian drones had been downed over the country in the past 24 hours.

Ukraine’s President Volodymyr Zelenskiy had vowed retribution on ​Friday following Russia’s heaviest drone and missile attack on Kyiv over a two-day period since the war ​started more than four years ago.Confirming the attack, Zelenskiy post a video on ⁠X of a drone in flight, columns of black smoke and fire crews trying to extinguish ​the flames.”Our responses to Russia’s prolongation of the war and its attacks on our cities and communities ​are entirely justified,” Zelenskiy said.He added that Ukraine was able to strike targets more than 500 km (310 miles) from the border despite dense Russian air defenses around Moscow.”We are clearly telling the Russians: their state must end its ​war,” he said.

Russia’s foreign ministry accused Kyiv of targeting civilians.”To the sound of Eurovision songs, the ​Kyiv regime, financed by the EU, carried out yet another mass terrorist attack,” TASS news agency cited the ministry’s ‌spokeswoman ⁠Maria Zakharova as saying.Both sides in the conflict deny deliberately targeting civilians. Ukraine has stepped up drone attacks on targets deep inside Russia in recent weeks, aiming to knock out oil refineries, depots and pipelines, as both sides seek to degrade each other’s infrastructure.

TASS cited Moscow Mayor Sergei Sobyanin as ​saying air defenses had destroyed ​81 drones headed for ⁠Moscow since midnight, making it the largest attack on the capital in more than a year.Sobyanin said 12 people were wounded, mostly near the ​entrance to Moscow’s oil refinery, while three houses were damaged. The “technology” of the ​refinery was ⁠not damaged, he added. Moscow regional Governor Andrei Vorobyov said a woman was killed when a home was hit in Khimki, north of the capital, adding that rescuers were searching the debris for another person. Two ⁠men ​were killed in the village of Pogorelki in the Mytishchi ​district.

Several residential high-rises and infrastructure facilities were damaged, he said. The country’s largest airport – Moscow’s Sheremetyevo – said drone debris had fallen on ​its territory without causing any damage.
