Saudi Arabia has arrested more than 120 people suspected of supplying or procuring fraudulent coronavirus vaccine and test certificates, official media said, two days before a tightly controlled Haj will begin.

The state-run SPA news agency said nine health ministry officials are among the accused, who have all pleaded guilty.

The suspects in the fraudulent certificates case are alleged to have used social media to advertise their services.

These included changing infection status, vaccination status and whether one dose or two had been administered, SPA reported.
