DUBAI: The US State Department has lambasted an Iranian airline for its role in spreading COVID-19, urging countries to “avoid the coronavirus and sanction risks by keeping Mahan Air out of your country.” State spokesperson Morgan Ortagus described the airline as a “deeply troubled weapons of mass destruction proliferator,” in a tweet on Saturday, adding how it “supports terrorism and the Maduro regime.” An earlier BBC investigation revealed Mahan Air, which has links to the Islamic Revolutionary Guards Corps (IRGC), continued flying to China and elsewhere for weeks after Tehran barred international flights on Jan. 31. Data showed flights continued until March despite the travel ban, and the BBC investigation established Iraq’s and Lebanon’s first coronavirus cases originated on Mahan Air flights.
