A Russian attack overnight, mostly targeting the capital Kyiv, killed four people and damaged buildings across the city, Ukrainian authorities have said
Russia, which launched a full-scale invasion of Ukraine in 2022, has in recent months intensified its attacks on infrastructure, particularly targeting Ukrainian energy facilities and rail systems, as well as residential areas.
"This was a deliberately calculated attack aimed at causing maximum harm to people and civilian infrastructure," President Volodymyr Zelensky said.
The attack killed four, Mr Zelensky said, and wounded dozens including a pregnant woman.

Mr Zelensky added that Russia had launched around 430 drones and 18 missiles in the attack.
AFP journalists in the capital saw tracer bullets used against drones and several anti-missile systems deployed.
"There are a lot of damaged high-rise buildings throughout Kyiv, almost in every district," Tymur Tkachenko, the head of the city's military administration, wrote on social media.
Ukrainian emergency services rescued dozens from fires and destruction across the city, as the police said 30 residential buildings in nine districts were damaged.
Kyiv mayor Vitali Klitschko said the city's heating system also suffered damage, with service interrupted in one district, but emergency outages had been resolved.
Three high-rise residential buildings were damaged in the Dniprovskyi district east of the Dnipro River, he added, with nine residents evacuated from one that was ablaze.
Pictures showed flames rising over the city at various sites, as residents huddled in rubble-strewn streets outside apartment buildings after the attack.
The governor of the Kyiv region outside the capital said drone and missile attacks injured six people, including a seven-year-old child, and triggered several fires.
Ukraine's air force said Russian drones and guided bombs were targeting several other regions.
Meanwhile Russia's defence ministry said its forces downed more than 200 Ukrainian drones overnight.
"During the past night, air defence assets intercepted and destroyed 216 Ukrainian unmanned aerial vehicles," the ministry wrote on Telegram, including 66 over Krasnodar Krai and 45 over Saratov in southern Russia.
The attack comes as Ukraine's Western allies increase pressure on Russia.
On Wednesday, Canada unveiled new sanctions targeting Russia's drone and energy production, as well as infrastructure used to launch cyberattacks.
G7 foreign ministers that day called for an immediate ceasefire in Ukraine, voicing "unwavering" support for the country's territorial integrity.
The European Commission is considering using part of Russia's assets frozen after its invasion to provide Kyiv with a loan for budgetary and military support over the next two years.
But after almost four years of war, both sides are heavily entrenched with Moscow rejecting ceasefire calls and efforts by US President Donald Trump to revive a long-stalled peace deal.
Russian forces have been grinding across eastern Ukraine for months, trying to take control of the Donetsk and Lugansk regions.
Russia said on Monday it had captured three more villages along the sprawling front line, where it is pressing its advantage in manpower and equipment.
Ukrainian President Volodymyr Zelensky visited troops near Ukraine's southeastern front yesterday, warning of the need to shore up the lines after losing ground in increasingly high-intensity battles far from Russia's offensive in the east.
Experts say Russia's latest strikes on energy infrastructure are putting Ukraine at risk of heating outages ahead of the winter months.
