Ukraine targeted Moscow with dozens of drones in a "massive" overnight attack, the city's mayor said on Tuesday, March 11.
"The Defense Ministry's air defense continues to repel a massive attack by enemy drones on Moscow," Sergei Sobyanin said on Telegram.
The mayor said that at least 60 drones were shot down, and that emergency services specialists were working at the site where debris fell.
Flights have been restricted in and out of two Moscow airports, Domodedovo and Zhukovsky.
No casualties have been reported, but the attack damaged the roof of a building, Sobyanin said in an online statement.
The attack on the Russian capital, hundreds of kilometers from the Ukraine border, comes ahead of an expected meeting Tuesday between top US and Ukrainian officials in Saudi Arabia.
Ukraine is set to present the United States with a plan for a partial ceasefire with Russia, hoping to restore support from its key benefactor, which under President Donald Trump has demanded concessions to end the three-year war.
The talks in Saudi Arabia will be the most senior since a disastrous White House meeting last month, when Trump berated Ukraine's President Volodymyr Zelensky for purported ingratitude.
Since Trump's dressing down of Zelensky, Washington has suspended military aid to Ukraine as well as intelligence sharing and access to satellite imagery in a bid to force it to the negotiating table.
