President Zelensky addressed Thursday British and Ukrainian nations at the fundraising event "Brave Ukraine", and said that Ukraine needs "a modern analogue of the Marshall Plan,” AFP reported.

He added that 6.5 billion dollars were raised at the International Donors' Conference, but "this is only part of what is really needed to restore normal life" in territories affected by the Russian military operation.

Earlier Thursday, more than six billion euros ($6.3 billion) were collected at a Ukraine donors' conference in Warsaw, Polish Prime Minister Mateusz Morawiecki said.

"At this conference, we were able to gather more than six billion euros and this money will be distributed to support Ukraine and all those who support Ukraine," Morawiecki told a news conference.

Zelensky on Thursday had launched a global crowdfunding platform to help Kyiv win the war with Russia and rebuild the country's infrastructure, according to AFP.

"In one click, you can donate funds to protect our defenders, to save our civilians and to rebuild Ukraine," Zelensky said in English in a video posted on his Twitter page.

"Every donation matters for victory."

Nine weeks into Russia's military operation, Ukrainian cities have suffered vast destruction.

"All funds will be transferred to the national bank of Ukraine and allocated to the relevant ministries," Zelensky said, indicating that his government would give an update "every 24 hours" about how the money was being used.

The Ukrainian leader called on ordinary people around the world to help Kyiv defeat Moscow.

"Only together we have the potential to stop the war and to rebuild what Russia has destroyed."

He said Ukraine will "always remember" their contributions.

It is not the first such fundraising effort launched by the Ukrainian government.

In mid-March, it launched a website with all donations funneled to Ukraine's central bank.

Offering donors the chance to give in 10 cryptocurrencies, including Bitcoin, ether, tether and dogecoin, the campaign was an immediate hit with its official website tweeting on March 19: "Over $60M contributed, with $10M donated in a few days!"

Kyiv has received Western military aid, but its army remains far smaller than Russia's.

Zelensky, 44, has addressed parliaments around the world on an almost daily basis, appealing for support amid Moscow's attack.
