Russian attacks killed two people late this evening in Ukraine's south eastern city of Zaporizhzhia and three more in the country's north and east, officials said.
Zaporizhzhia regional governor Ivan Fedorov, writing on the Telegram messaging app, said the city had been struck more than 10 times, killing two people and injuring eight.
Pictures posted online showed rescue teams sifting through rubble and apartment blocks and homes with windows and facades badly damaged.
In the Sumy region, on Ukraine's northern border with Russia, prosecutors said Russian forces dropped at least six guided bombs on the village of Krasnopillia, killing two people and injuring at least two.
In the eastern Donetsk region, the focal point of Russia's steady westward advance, prosecutors said Russian forces had dropped three bombs on the town of Kostiantynivka, close to the front lines, killing one person.
The Kremlin said this week that Russian President Vladimir Putin had agreed in a call with his US counterpart Donald Trump to observe a 30-day ceasefire on energy targets.
That accord fell short of a wider agreement that the US had sought, and which was accepted by Ukraine, for a blanket 30-day ceasefire. Talks on pursuing a ceasefire are scheduled for next week in Saudi Arabia and, separately, with Russian and Ukrainian officials.
Three injured, buildings damaged in Odessa
Russia pounded Ukraine's Black Sea city of Odesa with one of its biggest drone attacks, injuring three teenagers, damaging residential and commercial buildings, and sparking fires across the city, officials have said.
The attack came as the United States is pushing for a peace deal between Ukraine and Russia, and hoping to agree on a partial ceasefire that would halt strikes on energy infrastructure by both sides.
Czech President Petr Pavel, a vocal backer of Kyiv who has led an effort to source more than one million artillery shells for Ukraine's war effort, was in the city for talks with regional officials just before the attack.
Mr Pavel, who later met President Volodymyr Zelensky in Kyiv, told reporters he had left Odesa by train around 20 minutes before the explosions. The strikes showed how difficult it would be to negotiate with Moscow, he said.
"One has to be truly cynical when declaring the will to have peace negotiations or negotiations on a ceasefire, and at the same time to launch a massive attack on civilian infrastructure. It is extremely difficult to deal with such a party."
The long-range drones buzzed into the city in several waves, damaging infrastructure, residential houses, and commercial buildings, and causing multiple fires, officials said.
Around 25 cars had been set ablaze at a car repair shop.
"We could not do anything. We were just standing and watching as everything was on fire. I am in total shock," the shop's owner, who gave her name as Inna, told Reuters.
Oleksandr Kovalenko, a military analyst, said that Russia used new tactics for the attack, having its drones descend from a higher altitude than usual and at high speeds to make it harder for Ukraine's air defences.
He said it was one of the "most massive" attacks on Odesa since Russia invaded in February 2022: "It was intimidation. Terror against the civilian population."

Separately, Russia and Ukraine accused each other of attacking a major Russian gas pumping and measuring station that lies in a part of Russia's Kursk region that Moscow's forces have mostly recaptured from Ukraine this month.
Moscow said Ukraine had blown up the facility in an act of terrorism. Kyiv said Russian forces shelled it with artillery in "a provocation" and denied any involvement.
Both Russia and Ukraine have agreed during separate talks with US officials that they are ready for a moratorium on strikes on energy infrastructure. Moscow rejected a more comprehensive 30-day ceasefire.
Ukrainian, US and Russian delegations are due to meet in Saudi Arabia separately on Monday to discuss the details, officials have said.
Russia launched a total of 214 drones at Ukraine overnight, the air force said. It did not specify how many drones targeted Odesa.
The air force shot down 114 of the drones and said that another 81 drones were "lost", its term for those suppressed using electronic warfare defences.
Ukraine has used drones to continue striking targets in Russia, hitting oil infrastructure and a strategic bomber base in recent days.
