A Ukrainian strike in part of the northeastern Kharkiv region held by Russia killed at least three people and gravely wounded another on Saturday, according to the Moscow-backed authorities.
"Three civilians were killed and a woman was seriously wounded as a result of a strike by a Ukrainian drone on a car in the village of Pisky in the Kharkiv region," Vitaliy Ganchev, a local Russia-installed governor, wrote on Telegram.
Russia's defence ministry reported having shot down a total of 616 Ukrainian drones during the night across more than 20 regions of the country.
Several people were wounded as a result of falling drone debris, which also started fires, according to local Russian authorities.
Another drone barrage damaged industrial infrastructure in Togliatti, on the Volga river in southeastern Russia, said the city's mayor, Ilya Sukhikh.
Three bodies were pulled from the rubble after a Friday night attack on a factory in Oryol, about 370 kilometres (230 miles) southwest of Moscow, the Russian authorities said.
Five people were also seriously wounded and are in intensive care, according to the emergency services.
On the Ukrainian side, the air force said that Russia had launched at least 126 drones at Ukraine overnight, of which 101 were shot down.
Two people were wounded in the capital, Kiev, according to the emergency services.
Ukrainian attack cuts water, power in occupied Crimea
Meanwhile, a separate Ukrainian attack led to water and power cuts in occupied Crimea on Saturday, when a drone barrage hit southeastern Russia, according to the Russian authorities.
"As a result of an incident that occurred on the main power grids outside our region, caused by an enemy attack using a drone, restrictions on the supply of electricity and water have been put in place," Sergei Aksyonov, the Moscow-installed head of the Crimean peninsula, wrote on Telegram.
He did not specify the number of households affected in Crimea, which is home to more than 2.5 million people.
The peninsula, which was seized from Ukraine by Russia in 2014, is a regular target for Ukrainian attacks.
Ukraine says Starlink and Starshield operating at 400 kph after week of throttling
The Starlink satellite communications system and its military version Starshield are operating again at speeds over 400 km per hour, Kiev's defence minister said on Saturday, after over a week of service restrictions that slowed connections and disrupted military operations.
"The Ministry of Defence's monitoring systems are recording a return to normal speed for Starlink/Starshield. We are recording a speed of over 400 kph. The connection is stable," Evhenii Khmara told reporters.
The Ukrainian military does not disclose the systems' maximum operating speeds, and the defence ministry did not say whether service had been fully restored.
"Monitoring systems had previously recorded disruptions to the Starlink/Starshield service. The speed metrics have now returned to normal," the ministry said.
The restrictions, first reported on October 14, undermined Ukraine's ability to intercept Russian attack drones and disrupted frontline communications, Ukrainian officials said.
Sources said connection speeds had been reduced to about 160 kph or less.
Ukraine's problems with SpaceX-owned Starlink came after US President Donald Trump announced a deal to buy Russian diesel and waived new sanctions on Moscow while pressing Ukraine to stop striking Russian oil refineries.
Neither SpaceX boss Elon Musk nor the US government has acknowledged responsibility for restricting Starlink or Starshield in Ukraine. Both have said publicly that any such decision could only have been taken by the other.
