Debris from a downed drone hit a high-rise building near the Kashirskaya subway station in Moscow, according to Baza, a Russian news outlet. Other debris landed on a highway in the capital, Mr. Sobyanin wrote. Tass, the state news agency, published a photograph of scorch marks from an impact on a building.
Drones forced Russian air traffic controllers to close flights for up to five hours, according to Rosaviatsia, the Russian agency overseeing aviation safety and air traffic control. Thirty-four flights bound for Moscow diverted away from the capital overnight, according to the agency.
Closer to the Ukrainian border, a strike on an electrical substation in the Kursk region of Russia late Monday wounded two teenagers, the regional governor, Aleksandr Khinshtein, said in a post on social media. The attack cut electricity to the town of Rylsk, he wrote.
A Ukrainian National Guard major, Oleksii Hetman, told Ukrainian media that Ukraine had staged a surprise counterattack in the Kursk region, advancing back over territory Ukraine had retreated from this spring. It was not possible to independently verify the Ukrainian major’s account.
Although Russia’s attacks on Ukraine from the air have been intensifying this year, on the ground, Russian advances have mostly stalled.
The Institute for the Study of War, a United States-based analytical group, calculated that the Russian Army lost on average 153 soldiers killed or wounded for each square mile of territory captured in the Kursk region and inside Ukraine in the last four months of 2024. Over a comparable four-month period this year, the cost had risen substantially as advances slowed, with Russia losing on average 256 soldiers killed or wounded for each square mile of territory gained, according to the estimate.
