The CIA now believes the virus responsible for the COVID-19 pandemic most likely originated from a laboratory.

The Central Intelligence Agency (CIA) has assessed the virus that COVID-19 more likely originated from an accidential lab leak in China and not naturally, according to the statement released by the agency on Saturday.

The intelligence agency says it has a “low confidence” in its new finding, but this is further than it has ever gone in pinpointing the origin of a virus that killed millions worldwide.
