Ukraine has said on Saturday it had downed 74 out of 75 Russian attack drones overnight, in what Kyiv said was the biggest drone attack since the start of the invasion.
The Ukrainian army said Russia had launched a "record number" of Iranian-made Shahed drones, the majority of which were downed over the capital, Kyiv, causing power cuts in the centre of the city as temperatures dipped below freezing.
The drone attack came as Ukraine marked Holodomor Remembrance Day, commemorating the 1930s starvation of millions in Ukraine under Soviet dictator Joseph Stalin.
"The enemy launched a record number of attack drones at Ukraine; The main direction of the attack is Kyiv," the commander of Ukraine's air force, General Mykola Oleshchuk, said.
The air force said it had downed "74 out of 75" Shahed drones.
Kyiv authorities said five people were wounded in the capital, including an 11-year-old child, and that the air raid lasted six hours.
Falling drone debris had sparked fires and damaged buildings across the city, Kyiv Mayor Vitali Klitschko said.
Kyiv residents cleared smashed windows and other damage in the city's Dniprovsky district, with ambulances parked nearby.
One of the buildings that was damaged housed a nursery and another had part of its top floor destroyed.
Local resident Viktor Vasylenko said he had soothed his young daughter, who experienced "panic and nausea" during the long night-time attacks as they sheltered in a corridor.
The 38-year-old said his family always has "everything prepared" in case of such attacks but it was the first time one had hit so close.
"My wife thought that the house would collapse in half," he said.
Latvia's president, Edgars Rinkevics, on a visit to Kyiv during the attack, posted photos on social media inside a dark bomb shelter.

Dozens of buildings had their power cut off after the attacks but Ukraine's energy ministry said electricity was later restored.
Kyiv 'main target'
Kyiv's army said that while the "main target" of the attack was Kyiv, air defence had also been called into action across southern Ukraine and a guided missile had been destroyed over the central Dnipropetrovsk region.
There were power cuts across the region, authorities said.
Kyiv has warned of and prepared for a renewed Russian campaign targeting its energy grid as winter descends, fearing a repeat of events last year, when thousands were left without heat or light in freezing temperatures.
More than 21 months into Moscow's offensive, fighting is most intense in the east of Ukraine and is now centred around the city of Avdiivka, which is nearly encircled by Russian forces.
Kyiv authorities said it was "symbolic" that the capital had been the subject of such a large-scale attack on the day Ukraine marks Holodomor.
Every year on the fourth Saturday of November, at 4 p.m., we light a candle in commemoration of those who were killed during the Holodomor genocide.

I urge everyone who can and everyone who supports Ukraine around the world to light a candle today.

"More than 70 Shahed on the night of the Holodomor Remembrance Day. The Russian leadership is proud of the fact that it can kill," Zelensky also said on social media.
'Impossible' to forgive
Zelensky attended a ceremony with Kyiv's top military brass, holding candles, to mark the event.
Ukraine says Holodomor, Ukrainian for "death by starvation", was caused deliberately by Soviet's agricultural policies.
Moscow denies this, and says it was part of a wider famine that also affected Russian parts of the Soviet Union.
He said it was "impossible" for Kyiv to forgive or forget the "horrific crimes of genocide" and thanked the growing number of countries that had recognised Holodomor as a deliberate crime against Ukraine.
Zelensky said Russia's current attacks on Ukraine were possible because of what he called uncondemned crimes of the past.
"In the last century, famine came from Moscow. Now, we hear words of denial from there. And every one of these words of denial actually sounds like a confession," Zelensky said.
Ukraine has urged the West for more weapons to counter the Russian invasion, concerned that global attention has shifted to the Israel-Gaza conflict.
Drones have been extensively used in the conflict, with Ukraine also launching drones into Russia and annexed Crimea.
