MOSCOW, May 22, 2025 (BSS/AFP) - Air traffic around Moscow was disrupted on Thursday as the Russian capital came under a heavy drone attack, the city's mayor and the civil aviation authority said.

Russia has intercepted 23 drones flying towards Moscow since midnight (2100 GMT), Mayor Sergei Sobyanin wrote in a series of posts on Telegram.

"Emergency services specialists are working at the site of the fallen debris," he wrote.

The attack came a day after 27 drones were launched towards the city, according to the mayor. Russia deployed a record number of drones against Ukraine at the weekend, Kyiv said Sunday.

The two countries have deployed drones against one another on a near daily basis since Russia launched its military offensive on Ukraine more than three years ago, but Moscow has been rarely impacted.

On Thursday, flights were halted at multiple Moscow airports, Russia's aviation authority Rosaviatsiya said.

Planes have been grounded at the city's main Sheremetyevo airport, as well as at Vnukovo, Domodedovo and Zhukovsky, Rosaviatsiya said on Telegram.

Russian President Vladimir Putin has repeatedly rebuffed calls by Kyiv and the West for an unconditional and immediate ceasefire.

Russia now controls around a fifth of Ukraine, including the Crimean peninsula which it annexed in 2014.

The fighting has killed tens of thousands, forced millions to flee their homes and destroyed cities and villages across the east and south of Ukraine.
