Iran imposed a 10-day lockdown across most of the country to curb the spread of a fourth wave of the coronavirus pandemic, state media reported.

The lockdown affects 23 of the country’s 31 provinces, health ministry spokesman Alireza Raisi said.

Businesses, schools, theatres and sports facilities have been forced to shut and gatherings are banned during the holy fasting month of Ramadan that begins on Wednesday.

Iran’s coronavirus cases have surpassed 2 million with a new daily average of over 20,000 infections over the past week, according to the health ministry. It has reported more than 64,000 fatalities.
