Russian strikes wounded six people in Odesa including three children, the Ukrainian city's military administration has said.
"Drones attacked the residential, logistical, and energy infrastructure of our region," Odesa's military administration regional head Oleg Kiper said on Telegram.
Two children aged eight and 14 were wounded in the attack, as well as a seven-month-old baby, Sergiy Lysak, head of the city's military administration, said in a separate Telegram post.
A 42-year-old man was also wounded and is in "serious condition", he added. In his latest update he put the overall toll at six.
Mr Lysak said residential, logistical, and energy infrastructure was targeted. Parts of Odesa lost heating and water supplies.
Elsewhere Russian drones wounded two men in the Dnipropetrovsk region, its military administration head Vladyslav Gaivanenko said on Telegram.
In Russia meanwhile, two people were wounded in a drone attack on Tuapse in the Krasnodar Krai region, municipal leader Sergei Boiko said in a Telegram post.
The attack damaged a port berth and equipment at an oil refinery as well as homes.
Munitions strikes left three people wounded in the Belgorod region, its governor Vyacheslav Gladkov said on Telegram.
The strikes came after Ukraine denied launching a drone attack on one of Russian President Vladimir Putin's residences and accused Moscow of peddling falsehoods to manipulate talks on ending the war.
Ukrainian President Volodymyr Zelensky, who has called Russia's claim a "complete fabrication", said he would meet with leaders of Kyiv's allies on 6 January in France in a bid to renew peace efforts.
The Kremlin said yesterday it considered the alleged drone attack on Mr Putin's secluded residence in the Novgorod region to be a "terrorist act" and a "personal attack against Putin".
But it said it could not provide evidence for its claim as the drones were "all shot down".
US President Donald Trump said on Sunday that a deal was closer than ever to end Russia's invasion of Ukraine but reported no apparent breakthrough on the flashpoint issue of territory after new talks with the Mr Zelensky and Mr Putin.
