Ukraine launched one of its largest drone attacks of the war, firing nearly 800 drones at Russia, officials said Tuesday, a day after a Russian missile strike in Ukraine’s Kharkiv region killed at least 10 people.

The warring countries are locked in an escalating duel of long-range aerial strikes as fighting on the roughly 1,250-kilometer (780-mile) front line in eastern and southern Ukraine is restricted by large numbers of drones and ground robots threatening troop movements, analysts say.

Over the past year, Ukraine has devised and deployed domestically produced long-range drones for strikes deep inside Russia. Its drone technology has impressed governments and global defense manufacturers.

Kyiv officials aim to make the Russian public feel the war’s consequences and pressure Russian President Vladimir Putin into negotiating a peace settlement. Putin has so far shown no sign he intends to stop the invasion.

"Putin continues to drag out the war instead of accepting Ukraine’s realistic cease-fire proposals and ending the bloodshed," Ukrainian Foreign Minister Andrii Sybiha said in a post on X.

Russian air defenses overnight intercepted 791 Ukrainian drones over several Russian regions, as well as annexed Crimea and the Black and the Azov seas, the Defense Ministry in Moscow said, in what was the second-largest drone attack since January 2025, according to an Associated Press tally.

More than 600 Ukrainian drones flew towards the Moscow region, where 180 were shot down, Moscow Mayor Sergei Sobyanin said. He didn’t provide further details.

Officials reported no deaths or major damage.

In the Moscow region that surrounds but doesn’t include the Russian capital, three people were injured, Gov. Andrei Vorobyov said.

The overnight attack started a fire at a warehouse of Wildberries, Russia’s biggest online retailer, in an industrial zone. Ukraine has repeatedly targeted the company’s depots, which it says help supply the Russian military.

Wildberries said its facility sustained "insignificant damage."

A Russian missile strike on the village of Pechenihy in Ukraine’s Kharkiv region killed 10 civilians, according to preliminary information, said Oleh Syniehubov, head of the Kharkiv regional military administration.

Another 17 people were wounded, he said. Zelenskyy called it "a brutal attack” that damaged 10 homes, a cafe, a post office, a store and at least seven vehicles, according to Syniehubov.

"We will definitely respond to this Russian strike,” Zelenskyy said on social media.

Also, three people were killed and three others were wounded over the past day in Russian attacks on Ukraine’s Sumy region, including drone strikes and an explosive device blast, Ukraine’s National Police said.
