Russian air defenses on Tuesday foiled a Ukrainian drone attack on Moscow that prompted authorities to briefly close one of the city’s international airports, officials said, as a Western analysis said Russia has managed to slow Kyiv’s recently launched counteroffensive. The drone attack, which follows previous similar raids on the Russian capital, was the first known assault on the Russian capital since an abortive mutiny launched 11 days ago by mercenary chief Yevgeny Prigozhin.
