Scientists linked to Wuhan bat researchers have been accused of performing dangerous experiments on a Mers-like virus that could spark a pandemic.
A team from the University of North Carolina published a paper in Science Advances on Wednesday detailing how they had synthesised a Mers-like bat virus, and used it to infect human cells and humanised mice.
Mers is one of the deadliest viruses, killing around 35 per cent of people that it infects.
