Iran's official death toll from the new coronavirus rose by 92 to reach 4,869 on Thursday but a parliamentary report said the actual number could be much higher.
Health Ministry spokesman Kianush Jahanpur, speaking on state television, also said the total number of cases of people infected with the coronavirus has reached 77,995.
However, a report by the Iranian parliament's research center suggested that the coronavirus tolls might be almost twice as many as those announced by the health ministry.
"The assessment is that the actual mortality which has not been accounted for is 0.8 times the official figures. The number of infected cases could be 8 to 10 times the official figures," the report said.
