Ukrainian President Volodymyr Zelenskyy has launched a global crowdfunding platform to help Kyiv win its war with Russia.
The fund would also be used to help Ukraine rebuild infrastructure, he said.
"In one click, you can donate funds to protect our defenders, to save our civilians and to rebuild Ukraine," Zelenskyy said in a tweeted video in English to launch the United24 platform. "Every donation matters for victory."
Ukrainian cities have suffered devastation in the nine weeks since Russia launched its invasion.
"All funds will be transferred to the national bank of Ukraine and allocated to the relevant ministries," Zelenskyy said.
He indicated that his government would give an update "every 24 hours" about how the money was being used.
Zelenskyy urged ordinary people around the world to help defeat Moscow and said Ukraine would "always remember" their contributions.
"Only together we have the potential to stop the war and to rebuild what Russia has destroyed."
