Us intelligence agencies on Friday released an updated and more detailed declassified report on the origins of the coronavirus. 'The intelligence community may never be able to determine whether the Novel Coronavirus was transmitted from animals to humans or leaked from a laboratory, but they believe that the virus was not developed as a biological weapon and that Chinese officials had no prior knowledge of the virus prior to the initial outbreak,' the report said. The report says the Chinese government continues to block international investigations, refuses to share information and blames the U.S. and other countries.
