US Secretary of State Mike Pompeo on Sunday said "enormous evidence" showed the new coronavirus originated in a lab in China, further fueling tensions with Beijing over its handling of the outbreak.
Pompeo's comments came as Europe and parts of the United States prepared to cautiously lift virus lockdowns as signs emerge that the deadly pandemic is ebbing and governments look to restart their battered economies.
More than 245,000 people have been killed and 3.4 million infected worldwide by the virus, which has left half of humanity under some form of lockdown and pushed the global economy towards its worst downturn since the Great Depression.
US President Donald Trump, increasingly critical of China's management of the first outbreak in the city of Wuhan in December, claims to have proof it started in a Chinese laboratory.

Scientists believe the virus jumped from animals to humans, after emerging in China, possibly from a market in Wuhan selling exotic animals for meat.
- 'History of infecting the world' -
China denies the claims, and the US Director of National Intelligence office has said analysts are still examining the exact origin of the outbreak.
Pompeo, a former CIA chief, told the ABC he agreed that the COVID-19 virus was not man-made.
But Pompeo went further than Trump, citing "enormous" evidence that the virus originated in a Wuhan lab. He did not however present evidence to back up his claim.

"I think the whole world can see now, remember, China has a history of infecting the world and running substandard laboratories," he said.
Pompeo said early Chinese efforts to downplay the coronavirus amounted to "a classic Communist disinformation effort. That created enormous risk."
"President Trump is very clear: we'll hold those responsible accountable."
- Pressure from demonstrators -
US news reports say Trump has tasked US spies to find out more about the origins of the virus, as he makes China's handling of the pandemic a centerpiece of his campaign for the November presidential election.

The United States has the most coronavirus deaths in the world at more 67,600, with 1,450 recorded over the 24-hours late Sunday.

Florida is set to ease its lockdown Monday, as other US states wrestle with pressure from demonstrators -- some carrying weapons -- who have rallied against the restrictions.
In New York, the epicenter of the US outbreak, an emergency field hospital erected in Central Park is set to close as virus cases decline.
But dozens of New Yorkers were fined for violating social distancing guidelines as they flocked to beaches and parks in balmy weekend weather.
In Brazil, President Jair Bolsonaro railed against the country's lockdown in a speech to thousands of anti-confinement demonstrators, even as the national death toll rose above 7,000.
- 'Rules are not clear' -
Across the Atlantic, European nations prepared for cautious easing of restrictions.
Hard-hit Italy -- which reported its lowest daily toll since stay-at-home orders were imposed on March 10 -- is set to follow Spain in allowing people outside.
Starting Monday Italians will be allowed to stroll in parks and visit relatives. Restaurants can open for takeaways and wholesale stores can resume business, but there was some confusion over the rules.

Romans were doing aerobics on rooftop terraces and exercising indoors while squares in the city center were mostly empty on the last day that Italians were obliged to remain within 200 meters of their homes.
"On the one hand, we're super excited for the reopening, we're already organizing various activities the kids will be able to do with their grandparents outdoors," said Rome resident Marghe Lodoli, who has three children.
"On the other hand, it's disorientating. The rules are not clear, and we're not sure if just using common sense will do."
Italian authorities have said some preventative measures are still needed in a country that has the second-highest number of virus deaths.

The British government said the easing of coronavirus lockdown measures was likely to be gradual, as it announced a further rise in the overall death toll.
Most governments are sticking to measures to control the spread of the virus -- social distancing and masks in public -- and more testing to try to track infections even as they relax curbs.
Even as some European countries gradually lift restrictions, officials in Moscow -- the epicenter of the contagion in Russia -- urged residents to stay home.
With cases increasing by several thousand each day, Russia is now the European country registering the most new infections.
