Russia's foreign ministry has said a Ukrainian drone attack on a Russian oil depot was an attempt by Kyiv to disrupt peace initiatives.
Authorities in the southern Russian region of Krasnodar said a Ukrainian drone attack caused a fire at an oil depot near the village of Kavkazskaya.
The depot is a rail terminal for Russian oil supplies to a pipeline linking Kazakhstan to the Black Sea.
"It is absolutely clear that we are talking about another provocation specially prepared by the Kyiv regime and aimded at disrupting peace initiatives," said Russian foreign ministry spokesperson Maria Zakharova.
Russia also said it destroyed 132 Ukrainian drones in overnight attacks in several regions throughout the country, while Ukrainian authorities said Russian attacks in the east of the country killed two people overnight.
Authorities also said 10 people were wounded in a drone barrage in the town of Kropyvnytsky, including four children.
Following a phone call yesterday between Ukrainian President Volodymyr Zelensky and US President Donald Trump, Mr Zelensky said Kyiv was "ready" to pause attacks on Russia's energy network and infrastructure, a day after Russian President Vladimir Putin agreed to halt similar strikes on Ukraine.
Mr Zelensky also said he had discussed an offer from Mr Trump as part of a ceasefire bid for the US to own and run Ukraine's nuclear power plants.
The offer comes as some 30 military chiefs from countries keen to help protect an eventual ceasefire between Russia and Ukraine prepared for talks in Britain to discuss planning for a peacekeeping force.
"We talked only about one power plant, which is under Russian occupation," said Mr Zelensky, adding that he had "not felt any pressure" from Mr Trump to make concessions to Russia.
A wider ceasefire remains elusive, with Mr Putin insisting in his own call with Mr Trump on Tuesday that the West must first stop all military aid for Ukraine.
UK Prime Minister Keir Starmer and France's President Emmanuel Macron have said they are willing to put British and French troops on the ground in Ukraine.
The UK government said a "significant number" of nations are prepared to do the same, but it is not clear exactly how many countries are keen.
Mr Trump's tone yesterday was markedly more positive after the call, with the White House describing it as "fantastic" - despite the fact that the two men had a televised row in the Oval Office recently.
Mr Trump "discussed Ukraine's electrical supply and nuclear power plants" and said the US could be "very helpful" in running them," National Security Advisor Mike Waltz and Secretary of State Marco Rubio said in a joint statement.
"American ownership of those plants would be the best protection for that infrastructure," it said.
Mr Trump also pledged to help Ukraine get more air defence equipment from Europe and to find Ukrainian children "abducted" by Russia, the statement said.
The US President earlier said on his Truth Social network that efforts to reach a full truce were "very much on track".
Mr Zelensky said Ukrainian and US officials could meet in coming days for fresh talks in Saudi Arabia, where Russian and American teams are also due to meet early next week.
Russia and Ukraine exchanged 372 prisoners, Moscow said yesterday, which was planned as a goodwill gesture following the Trump-Putin call.
However, Ukraine and Russia have accused each other of continuing attacks.
'Don't believe Putin'
The major sticking point remains Mr Putin's resistance to a full ceasefire - something that Ukraine and some Western allies say underscores how the Russian leader cannot be trusted.
Mr Putin insisted during his call with Mr Trump on Tuesday that a full ceasefire was only possible if the west agree to Moscow's long-standing demand to halt its billions of dollars in military aid for Ukraine.
The Russian president also demanded Ukraine must not be allowed to rearm and must halt mandatory mobilisation.
Russia and the US were even at odds on the results of the call.
The Kremlin said they only discussed halting power plant attacks, but the White House insisted the talks covered both energy and other civilian infrastructure.
Mr Trump's overtures to Mr Putin, and indications Washington will no longer guarantee European security, have also spooked Ukraine and the United States' NATO allies.
