Testing of the malaria drug hydroxychloroquine as a possible treatment for coronavirus has been halted because of safety fears, the World Health Organization (WHO) says.
Trials in several countries are being “temporarily” suspended as a precaution, the agency said on Monday.
It comes after a recent medical study suggested the drug could increase the risk of patients dying from Covid-19.
President Donald Trump has said he has taken the drug to ward off the virus.
The US president has repeatedly promoted the anti-malarial drug, against medical advice and despite warnings from public health officials that it could cause heart problems.
