At least seven people were killed in Russia after what officials called the "largest-scale" attack launched by Ukraine this year.
About 822 drones were used, 600 of which were aimed at Moscow, which suffered "one of the most massive drone attacks in recent times," regional governor Andrei Vorobyov said.
The warehouse of the Russian online retailer "Wildberries" was hit, reports CNN.
Officials in Belgorod, which borders the Ukraine, said a woman was killed after a civilian bus was hit, while an 83-year-old man was killed in a drone strike in the Moscow region.
The Russian state agency TASS reports that many drones targeted the Moscow area where a large part of the Russian elite lives.
Near Moscow
Moscow Mayor Sergei Sobyanin said the Wildberry warehouse in Koledino, 25 kilometers from central Moscow, was hit in an attack that injured three people. Video footage shows the fire and a large plume of smoke above the warehouse.
"Wildberrys", known as the Russian version of Amazon, has been the target of Ukrainian attacks several times. Kiev said it targeted logistics centers used by Russians to buy military equipment.
The Ministry of Defense of Ukraine announced that seven of the ten largest logistics centers of the company were "disabled".
Both warring parties accuse each other of targeting civilians.
"I want Russia to disappear"
In Ukraine, a 66-year-old man and a 64-year-old woman were killed after a private house was hit by a guided missile in the Zaporozhye region, officials said.
Two more people died in Kryvyi Rih, a city in Dnipropetrovsk. There were also victims in Sumy, Donetsk and Kherson.
In Kiev, air raid sirens went off four times overnight as the Ukrainian capital came under Russian attack. At least six people, including a child, were injured, Mayor Vitaly Klitschko said.
Russia said its attacks on Kiev were aimed at the facility Fire Point which produces parts for Ukraine's Flamingo missiles and a factory that produces components for drones.
A bookstore in the city district of Počajna was damaged in the attacks. Burnt books could be seen lying on the ground as firefighters extinguished the flames.
The husband of sixty-nine-year-old Valentina had a stall at the market.
Looking through the rubble, she told the BBC: "All these books on the street are from my husband's market stall - I recognize them on the floor."
She added: "You never think it's going to happen to you."
Record store owner Ljuba, 42, said she lost 500.000 hryvnias (£8.262) worth of stock.
"This job was my baby - many of the destroyed records were rare and irreplaceable," she told the BBC. "I want Russia to disappear from this Earth."
