Russia launched a pre-dawn attack on Ukraine's capital on Tuesday, killing at least one person and sending Kyiv's residents again scrambling into shelters to escape a relentless wave of daylight and nighttime bombardments.
Moscow authorities also reported a drone attack on the Russian capital.
At least 20 Shahed drones were destroyed by air defence forces in Kyiv's airspace in Russia's third attack on the capital in 24 hours, according to the Kyiv Military Administration.
The buzzing of drones could be heard over the city, followed by loud explosions as they were taken down by air defence systems.
In Moscow, residents reported hearing explosions and Mayor Sergei Sobyanin later confirmed there had been a drone attack.
Sobyanin said in a Telegram post that the attack caused "insignificant damage" to several buildings and that no one has been seriously hurt, without elaborating.
Residents of two buildings damaged in the attack were evacuated, Sobyanin said.
There was no immediate comment on the attacks from Ukrainian officials.
It was the second reported attack on Moscow, after authorities said two drones targeted the Kremlin earlier this month in what was labelled an attempt on President Vladimir Putin's life.
In the attacks overnight on Kyiv, one person died and three were injured when a high-rise building in the Holosiiv district caught fire. It was not immediately clear what caused the blaze but frequently the falling debris from drones being hit and the interceptor missiles have caused damage on the ground.
The building's upper two floors were destroyed, and there may be people under the rubble, the Kiyv Military Administration said. More than 20 people were evacuated.
Resident Valeriya Oreshko told The Associated Press in the aftermath that even though the immediate threat was over, the attacks had everyone on edge.
"You are happy that you are alive, but think about what will happen next," the 39-year-old said.
Oksana, who only gave her first name, said the whole building shook when it was hit.
"Go to shelters, because you really do not know where it (the drone) will fly," she advised others. "We hold on."
Elsewhere in the capital, falling debris caused a fire in a private house in the Darnytskyi district and three cars were set alight in the Pechersky district, according to the military administration.
The series of attacks that began on Sunday included a rare daylight attack on Monday, when Russian forces fired 11 ballistic and cruise missiles at Kyiv about 11.30 am, according to Ukraine's chief of staff, Valerii Zaluzhnyi. All of them were shot down, he said.
Debris from the intercepted missiles fell in Kyiv's central and northern districts during the morning, landing in the middle of traffic on a city road and also starting a fire on the roof of a building, the Kyiv military administration said. At least one civilian was reported hurt.
The Russian Defense Ministry said it launched a series of strikes early Monday targeting Ukrainian air bases with precision long-range air-launched missiles. The strikes destroyed command posts, radars, aircraft and ammunition stockpiles, it claimed. It didn't say anything about hitting cities or other civilian areas.
