Iran was accused of covering up the impact of the coronavirus amid fears that the infection could spread through the region because of the country’s poor health care standards.
Ten new cases were confirmed in Iran on Saturday, bringing the total to 29, and the death toll rose to six — the highest outside China.
Most of the cases have been in Qom, where schools and universities are closed from Sunday.
The US State Department said the Iranian regime was playing down the danger and giving people “incorrect information.”
Online posts compared Iran’s coronavirus announcements with the attempted cover-up after the Islamic Revolutionary Guard Corps shot down a Ukrainian passenger plane last month, killing 176 people.
The World Health Organization said it was worried about the spread of the virus from Iran.
