Russia said it shot down nearly 300 Ukrainian drones overnight into Wednesday in one of the most extensive aerial assaults of the war, with dozens of the UAVs targeting the Moscow region and causing widespread flight disruptions.

According to the Russian Defense Ministry, a total of 296 drones were intercepted over 12 regions, including the capital. Moscow Governor Andrei Vorobyov reported that at least 42 drones were downed over the Moscow area alone, with three residential homes damaged in the town of Chekhov, roughly 40 miles south of the city.

The barrage forced temporary airspace closures and delays at Moscow’s Sheremetyevo International Airport, one of four major airports serving the capital. Similar flight disruptions have become increasingly common in recent weeks amid Ukraine’s stepped-up long-range drone operations.

On the Ukrainian side, officials suggested that some of the strikes may have hit strategic targets. Andriy Kovalenko, who heads Ukraine’s Counter-Disinformation Center under the National Security and Defense Council, claimed on Telegram that Tuesday night’s attacks produced “some pretty good hits.”

Among the purported targets was the Dubna Machine-Building Plant, located about 70 miles north of Moscow, which Kovalenko said is involved in aviation, missile, and drone production. He also claimed that the Technopark ELMA-Zelenograd facility, which develops microelectronics, robotics, and medical technology—and plays a key role in replacing Western-imported components—was targeted.

ABC News has not independently verified these claims of successful strikes.

The surge in Ukrainian drone activity marks a continued shift in the conflict, with Kyiv increasingly seeking to hit Russian military and industrial infrastructure far from the front lines.
