The world's largest economy, United States, has suffered the deadliest coronavirus outbreak.
The United States on Friday recorded its steepest job losses in history over the coronavirus pandemic as Europe moved to keep its borders shut for another month.
Hopes have been rising that the worst of the global catastrophe, which has killed more than 270,000 people, has passed, and the United States on Friday approved a new at-home saliva test to speed up diagnosis for COVID-19.
But after weeks in which half of humanity was restricted from carrying on normal life, the effects have been painfully visible, with the global economy suffering its most acute downturn in nearly a century.
Parades and commemorations to mark 75 years since Nazi Germany's surrender were canceled or scaled down, and the thoughts of many national leaders were on fighting the new global challenge.
"We want more, not less, cooperation in the world -- also in the fight against the pandemic," German President Frank-Walter Steinmeier said.
Russia, which marks the occasion a day later than western Europe, was on Saturday preparing for muted celebrations after becoming Europe's hotspot in the coronavirus pandemic.
A Red Square parade has been postponed and President Vladimir Putin will instead give a 20-minute speech at a war memorial inside the Kremlin walls.
The world's largest economy
In the United States, 20.5 million jobs were wiped out in April -- the most ever reported -- with unemployment rising to 14.7 per cent, the highest since the Great Depression.
The world's largest economy has suffered the deadliest coronavirus outbreak, with more than 77,000 fatalities and nearly 1.3 million cases.
Mindful of elections in November, President Donald Trump has nonetheless vowed to reopen the country, and a growing number of state governors have already let business resume with precautions.
Trump played down the unemployment numbers, as the White House pointed to substantial gains Friday on global stock markets as proof that better times were ahead.
"We're going to have a phenomenal year next year," Trump told reporters. "I think it's going to come back blazing."
His optimism came even as the virus spread within the White House, with the press secretary of Vice President Mike Pence testing positive.
Neighbouring Canada also shed three million jobs, bringing its unemployment rate up to 13.1 percent, two days after the European Union forecast a massive recession in the bloc.
No unity at UN
Far from bringing the world together, the crisis has triggered a war of words between China, where the virus first appeared in the metropolis of Wuhan, and the United States, where Trump has battled criticism over his handling of an epidemic which he boasted of having under control in January.
The Trump administration has brought into the mainstream a theory that the virus came from a Wuhan laboratory, despite the World Health Organization and the top US epidemiologist saying there is no evidence.
China rejects the charge, and America's allies are not convinced.
The feud spread Friday to the UN Security Council, where the United States, stunning other members, prevented a vote on a resolution that called for a ceasefire in various conflicts around the world.
The resolution, led by France and Tunisia, called for a cessation of hostilities in conflict zones and a 90-day "humanitarian pause" to allow governments to better address the pandemic among those suffering most.
Diplomats said the United States was concerned about language in the resolution on the role of the World Health Organization, which has been at the forefront of confronting COVID-19.
Trump has vowed to freeze the more than $400 million in annual US funding for the UN body, saying it did not act quickly enough when the mysterious respiratory disease emerged in Wuhan and blindly took the word of China.
The US State Department on Friday also accused China and Russia of sharply escalating disinformation online about the virus, including promoting conspiracy theories that it was cooked up by US scientists.
Trump, in a rare Oval Office address to the nation on Wednesday night, said the month-long restriction on travel would begin late on Friday, at midnight. After days of playing down the coronavirus threat, he blamed Europe for not acting quickly enough to address the "foreign virus” and claimed that US clusters were "seeded” by European travellers.
The company has hundreds of retail stores worldwide, including 42 in China that closed or operated with reduced hours at the height of the country's outbreak.
The ministers' video conference dragged on for over 15 hours from Tuesday into Wednesday, with Italy and Spain pleading for a solidarity fund that would be paid for by European partners jointly borrowing money on the financial markets.
As health officials issued warnings on Tuesday against reopening economies too quickly, the coronavirus struck inside some of the world’s superpowers, with a top aide to Russian President Vladimir Putin diagnosed just days after US Vice President Mike Pence's press secretary also tested positive.
Taiwan scrambled fighter jets on Friday as 18 Chinese aircraft buzzed the island, including crossing the sensitive mid-line of the Taiwan Strait, in an escalation of tensions as a senior US official held talks in Taipei.
Two Turkish soldiers were killed and another was wounded after Kurdish militants fired rockets at a military base in northern Iraq, Turkey's Defence Ministry said in a statement on Friday.
Australia said on Friday it would increase the number of citizens allowed to return home each week to 6,000 as it manages to get new COVID-19 infections under control.
