Iran reported 8,751 new COVID-19 cases on Sunday, raising its nationwide caseload to 1,855,674.
The pandemic has so far claimed 62,397 lives in Iran, up by 89 in the past 24 hours, said Sima Sadat Lari, spokeswoman for the Iranian Ministry of Health and Medical Education, during her daily briefing.
Of the newly infected, 1,049 were hospitalized, Lari added.
A total of 1,593,219 people have recovered from the disease and been discharged from hospitals, while 3,928 remain in intensive care units, she noted.
According to the spokeswoman, 12,618,420 tests for the virus have been carried out in Iran as of Sunday.
Currently, 23 Iranian cities are on red alert for a high risk of infection, while 44 others are on orange alert for a medium risk, the spokeswoman said.
On Saturday, Iranian President Hassan Rouhani blamed Washington's sanctions for "hindering the availability of COVID-19 vaccines" for Iranians.
"We order a country for a (COVID-19) vaccine, it says it is still afraid of U.S. sanctions," Rouhani was quoted as saying by the official Islamic Republic News Agency.
Rouhani noted that his administration has allowed the private sector to import COVID-19 vaccines, using the subsidized foreign currency and under the supervision of the Ministry of Health and Medical Education.
