A "massive" overnight Russian attack on central and southeastern Ukraine killed one person and injured at least 24 others, authorities have said.
The regional governor of Zaporizhzhia, Ivan Fedorov, said on the Telegram messaging app that the attack damaged infrastructure and residential buildings.
"At night, the enemy carried out massive strikes" on Zaporizhzhia, Ukraine's state emergency service said on Telegram earlier.
Two children were among those injured in the attack.
"Russian strikes destroyed private houses, damaged many facilities, including cafes, service stations, and industrial enterprises," Mr Fedorov said.
Ukraine's central Dnipropetrovsk region also came under attack early today, the governor said, reporting strikes in Dnipro and Pavlograd.
"The region is under a massive attack. Explosions are being heard," Sergiy Lysak wrote on Telegram, warning residents to take cover.
The Ukrainian air force said it had downed 510 of 537 drones and 38 of 45 missiles launched by Russia in the overnight attack.
It recorded five missile and 24 drone hits at seven locations with debris falling on 21 sites, according to the statement on Telegram.
Meanwhile, Ukrainian president Volodymyr Zelensky said that Moscow had used preparation time for a meeting of leaders of both countries to launch new massive attacks on his country.
"The only way to reopen a window of opportunity for diplomacy is through tough measures against all those bankrolling the Russian army and effective sanctions against Moscow itself - banking and energy sanctions," Mr Zelensky wrote on X.
No date has been set yet for the bilateral meeting.
Since Russia launched its full-scale invasion of Ukraine in February 2022, Dnipropetrovsk had been largely spared from intense fighting.
But Kyiv acknowledged on Tuesday that Russian troops had entered the region, after Moscow claimed its troops had gained a foothold there.
Dnipropetrovsk is not one of the five Ukrainian regions - Donetsk, Kherson, Lugansk, Zaporizhzhia and Crimea - that Moscow has publicly claimed as Russian territory.
Meanwhile the Tánaiste and Minister for Foreign Affairs and Defence has said that more has to be considered in relation to sanctions against Russia.
Speaking ahead of a meeting of EU foreign ministers in Copenhagen, Simon Harris said that there needs to be more robust sanctions against Russia.
"Today, I'd be very eager that we come together to have a proper conversation about what more can be done to actually make talks about peace in Ukraine a reality," he said.
"While Putin is talking about peace, he's absolutely doing nothing to indicate any willingness to bring it about. In fact, his reign of terror continues."
