Moscow Mayor Sergei Sobyanin said that all the drones were flying toward the Russian capital.

Due to the drone attack, all four Moscow airports — Sheremetyevo, Vnukovo, Domodedovo and Zhukovsky — as well as airports in Tambov and Vladimir were temporarily closed.

Other Ukrainian drones were also shot down over the Oryol, Kursk, Belgorod, Tula, Kaluga, Voronezh, Lipetsk, Smolensk and Bryansk oblasts, the Russian Defense Ministry said.

Tula Oblast Governor Dmitry Milyaev stated one of the drones crashed into the roof of an apartment building in Tula. The attack also damaged other residential and non-residential buildings, he added.

Russian authorities haven’t reported any other damage or reported any casualties.

Kyiv hasn’t commented on the attack.

Ukraine regularly launches drone attacks against Russian military and industrial facilities in the rear to undermine Russia’s ability to wage its all-out war.

Moscow and surrounding regions have faced a growing number of Ukrainian drone incursions in recent weeks.

A day before on May 21, Ukrainian drones struck Russia’s Bolkhov semiconductor plant in Oryol Oblast, which produces parts for Sukhoi warplanes and Iskander and Kinzhal missiles, Ukraine’s General Staff claimed.

On May 19, Trump held a phone call with Russian President Vladimir Putin, marking their first known conversation in two months.

“We are trying to settle Russia-Ukraine,” Trump told reporters, adding, “I spoke with President Putin for two hours the day before yesterday. I think we made a lot of progress. But that’s a bloodbath.”

Trump described the war as “a horrible thing.”

“There’s a lot of hatred, a lot of deaths,” he continued, stating, “I get satellite pictures of that field — you never saw anything like that in your life.”

The recent call between two leaders came days after largely inconclusive negotiations in Istanbul, where Russia sent a delegation of low-level officials and reiterated sweeping territorial demands, including that Ukraine accept the loss of Crimea and four other regions.

After the call, Putin reiterated Russia’s maximalist demands, denying full ceasefire agreement.

Trump has been inconsistent in his rhetoric toward the Russian leader, at times voicing frustration with the stalled peace efforts but mostly avoiding direct criticism of Putin.

Despite U.S. efforts, Putin has shown little willingness to compromise to achieve a settlement.

Trump’s approach has caused frustration and confusion among European allies, many of whom wanted him to back a joint U.S.–EU ultimatum for an unconditional ceasefire starting May 12 and tougher sanctions on Moscow. Despite Russia’s refusal, no additional U.S. sanctions have so far been imposed.

Trump has often boasted about his supposedly warm ties with the Russian leader, though the two have not met since Trump returned to office this January.

The two presidents previously held a phone call on March 18, during which Putin rejected Trump’s Kyiv-backed offer for a 30-day ceasefire but declared a pause on strikes against energy facilities, which Ukraine announced was repeatedly violated.

Trump has adopted a more critical rhetoric toward the Kremlin recently amid Moscow’s delays in peace negotiations and continued attacks on civilian areas in Ukraine.

At the same time, the new U.S. administration has also often used a scathing tone toward Ukraine, most notably during an explosive meeting between Trump and President Volodymyr Zelensky in the White House in February. The two leaders held a second meeting on the sidelines of Pope Francis’s funeral in April, which was described by both parties in more positive terms.
