The number of coronavirus deaths in Iran is three times what the government claims, a BBC Persian service investigation has found.
The government’s own records appear to show almost 42,000 people died from Covid-19 symptoms up to 20 July, versus 14,405 reported by its health ministry.
Similarly, the number of infections is double official figures: 451,024 as opposed to 278,827.
The data was sent to the BBC by an anonymous source.
There have been irregularities in data between national and regional levels. Some , local authorities have spoken out and statisticians have tried to give alternative estimates.
