Ukrainian President Volodymyr Zelensky has said a meeting with Russian counterpart Vladimir Putin would be "the most effective way forward" amid stalled diplomatic attempts to end the war as he celebrated Ukraine's Independence Day.
Ukraine launched drone strikes on Russia, triggering a fire at a nuclear power plant as Ukrainians marked their Independence Day with the conflict now in its fourth year.
After a push by US President Donald Trump to broker a Ukraine-Russia summit, hopes for peace dimmed when Russia on Friday ruled out any immediate Putin-Zelensky meeting.
But Mr Zelensky this afternoon said the "format of talks between leaders is the most effective way forward", renewing calls for a bilateral summit with Mr Putin.

Russian Foreign Minister Sergei Lavrov earlier accused Western countries of seeking "a pretext to block negotiations" and slammed Mr Zelensky for "demanding an immediate meeting at all costs".
Mr Zelensky vowed to "to push Russia to peace" as he spoke at a ceremony attended by US envoy Keith Kellogg - whom he awarded with the Ukrainian Order of Merit - and other Western officials.
With the war having already claimed tens of thousands of lives, Russia has recently claimed new advances, including taking two villages in the eastern Donetsk region yesterday.

Ukrainian commander-in-chief Oleksandr Syrsky said that three other villages had been reclaimed in Donetsk, that has emerged as the focal point for peace talks.
Ukraine's Independence Day drone attacks in Russia included one shot down over the Kursk Nuclear Power Plant in western Russia.
The plant said a fire sparked by the drone had been extinguished and there were no casualties or increased radiation levels.
The International Atomic Energy Agency has repeatedly warned of the risks from fighting around nuclear plants following Russia's full-scale invasion launched in February 2022.

Russian authorities said Ukrainian drones had also been shot down over areas far from the front, including Saint Petersburg in the northwest.
Ten drones were shot down over the port of Ust-Luga on the Gulf of Finland, sparking a fire at a fuel terminal owned by Russian energy group Novatek, local authorities said.
Ukraine's outgunned army has relied heavily on drones to respond to Russia's invasion, notably targeting oil infrastructure to hit a key source of Moscow's revenues to fund the war.
Russia has seen soaring fuel prices since the attacks began.
Ukraine meanwhile said Russia had attacked with a ballistic missile and 72 Iranian-made Shahed attack drones, 48 of which the air force said had been shot down.
A Russian drone strike killed a 47-year-old woman in the eastern region of Dnipropetrovsk, the governor said.
Ukraine and Russia also said earlier they had each sent back 146 prisoners of war and civilians in the latest of a series of swaps that remain one of the few areas of cooperation between the rivals.

'Ukraine is a fighter'
Speaking at the ceremony to mark the anniversary of Ukraine's 1991 independence after the break-up of the Soviet Union, Mr Zelensky said: "This is how Ukraine strikes when its calls for peace are ignored."
"Today, both the US and Europe agree: Ukraine has not yet fully won, but it will certainly not lose. Ukraine has secured its independence. Ukraine is not a victim; it is a fighter."
He said the presence of foreign troops in Ukraine once the war ends would be "important" as Kyiv seeks to work on potential security guarantees with its allies.
Canadian Prime Minister Mark Carney on a visit to Kyiv said it was not "the choice of Russia how the future sovereignty, independence, liberty of Ukraine is guaranteed."
Mr Zelensky thanked other world leaders including Donald Trump, Chinese President Xi Jinping, French President Emmanuel Macron, Britain's King Charles and Pope Leo for sending messages to mark the occasion.
Norway announced it would contribute seven billion kroner ($700 million) as part of its joint pledge with Germany to provide Ukraine with two complete US Patriot systems that Germany already possesses.
The systems are in Germany and will be delivered to Ukraine "as soon as possible", the Norwegian government said.
Russia now controls around a fifth of Ukraine, including the Crimean peninsula, which it annexed in 2014.
Mr Putin has repeatedly rebuffed calls from Ukraine and the West for an immediate ceasefire.
The fighting has forced millions of people to flee their homes and destroyed cities and villages across eastern and southern Ukraine.

Vance cites 'significant concessions' by Russia on Ukraine
Meanwhile, US Vice President JD Vance rejected suggestions Moscow is slow-walking a potential peace deal in Ukraine, saying Russia has made "significant concessions" to Mr Trump over its demands for ending the war.
In a pre-recorded interview, Mr Vance insisted Mr Trump, who met Mr Putin this month at an Alaska summit, has been engaged in "very aggressive, very energetic diplomacy" with both Moscow and Kyiv in a bid to find a compromise solution that would stop the killing.
"I think the Russians have made significant concessions to President Trump for the first time in three and a half years of this conflict," Mr Vance told NBC.
"They've actually been willing to be flexible on some of their core demands."
Mr Vance said Moscow has conceded "the recognition that Ukraine will have territorial integrity after the war" - although he notably did not address whether a post-war Ukraine would have the boundaries it did before Moscow's invasion.
He also stressed that Russia has "recognised that they're not going to be able to install a puppet regime in Kyiv."
"Again, have they made every concession? Of course, they haven't," he added "But we're making progress."
