FBI chief Christopher Wray says China lab leak most likely

FBI Director Christopher Wray has said that the bureau believes Covid-19 most likely originated in a Chinese government-controlled lab.

"The FBI has for quite some time now assessed that the origins of the pandemic are most likely a potential lab incident," he told Fox News.

It is the first public confirmation of the FBI's classified judgement of how the pandemic virus emerged.

Many scientists point out there is no evidence that it leaked from a lab.

And other US government agencies have drawn differing conclusions to the FBI's.

Some of them have said - but with a low level of certainty - that the virus did not start in a lab but instead jumped from animals to humans.
