British music stars Harry Styles and Ed Sheeran, United States basketball legend Shaquille O'Neal and other celebrities will donate personal objects for a campaign launched on Saturday to support healthcare in Ukraine.

Seven months into Russia's war, the WHO Foundation—an independent organization that works to raise funds to support the United Nations health agency's work addressing global health crises—launched the Human Kind e-store, where fans can try to win items donated by their favorite celebrities.

The funds raised will go towards supporting WHO's actions in war-ravaged Ukraine and neighboring countries, the foundation said, adding that it aimed to raise US$53.7 million.

Harry Styles has donated a signed vinyl, while Shaquille O'Neal, Ukrainian footballer Vitaliy Mykolenko and other sports legends have donated signed shirts and jerseys.

Wladimir Klitschko, a former heavyweight boxing champion and brother of Kyiv's mayor, has donated a boxing glove.

The star-studded line-up also includes British singer Ellie Goulding and American artist Shepard Fairey.

British pop legend Annie Lennox, who donated a pair of iconic sunglasses, said images from Ukraine, including of women giving birth in basements, were "profoundly shocking”.

"I encourage everyone to do what they can to support the people of Ukraine through this crisis," she said in the foundation's statement, insisting that "healthcare is a human right that all deserve access to”.

Raffle tickets for the items cost between 5 and 10 pound sterling ($5.40 and $10.90) on the humankind.who.foundation website from Sept. 24 to Oct. 24, with winners set to be drawn on Oct. 31, the foundation said.

"Seven months into this tragic war, people are ever more in need of urgent medical care across the country," foundation chief Anil Soni said in the statement.

"We must address the immediate and long-term health needs of those affected."

Since Moscow invaded its western neighbor on Feb. 24, the WHO has verified 550 attacks on healthcare in Ukraine.

More than 5,900 civilians have died, and more than 8,600 have been injured, while over 12 million Ukrainian refugees are currently in Europe as a result of the war, the WHO said.

Meanwhile, some 17.7 million people—over a third of Ukraine's population—need humanitarian assistance.
