Rupert Colville, spokesperson for the UN High Commissioner for Human Rights, told reporters that Iran prisons are severely overcrowded. "It's impossible to isolate people and enforce physical distancing because of lack of space," he said. A report carried on Wednesday by Mizanonline, the official website of the Iranian judiciary, denied prisons were in poor condition. It said 18 preventative measures had been taken in the past three months, including continuous testing of prison staff for the coronavirus, distribution of required medical items, isolation for infected prisoners and social distancing during family visits. Colville said political prisoners include conservationists, dual nationals, human rights defenders, and lawyers, such as Nasrin Sotoudeh, who has been sentenced to 33 years for various charges under national security laws. The Iranian judiciary said in March that it had temporarily released about 85,000 inmates in response to the coronavirus, including people held on security charges who say they are political prisoners; in late May many were returned to prison.
