Tickets have gone on sale for Formula One's season opening Bahrain Grand Prix but are limited to individuals who have either been fully vaccinated against COVID-19 or have recovered from the virus.
The race will take place on March 28 and kick off this year's 23-race season.
Formula One has always maintained that it will welcome fans back to races when it is safe to do so, but Bahrain is the first venue to limit ticket sales to vaccinated individuals and those who have recovered.
The Bahrain International Circuit said the decision had been taken "in line with government health advice" and those buying tickets must be able to prove their eligibility via the BeAware Bahrain app.
