Passengers from more than 150 nations will be banned from transiting through Hong Kong, its airport said Friday, in the latest ramping up of the city's strict anti-coronavirus travel measures.

 "Passenger transfer/transit services via Hong Kong International Airport for any persons who have stayed in Group A specified place(s) in the past 21 days will be suspended," the airport said in a statement on its website.

 The suspension will come into force on Sunday, for a month.
