Iran-Iraq border points will be closed for passengers until April 4, Hossein Qasemi, director-general of border affairs of Iranian Interior Ministry, told IRNA news agency.
The decision was made by the National Headquarters for Fighting Coronavirus following the request of the Ministry of Health and Medical Education, Qasemi was quoted as saying.
Previous reports said that Iran-Iraq border crossings would remain open to cargo trucks.
However, if there are Iranian nationals in Iraq who want to come back to Iran, or if Iraqi nationals in Iran want to go back to their country, they can cross the border, he said.
Also, border crossing for traders, contractors and engineering activities would be possible after necessary evaluations, he added.
Iran closed several crossing points with Iraq in February to stem the spread of a new variant of COVID-19.
