In wake of new coronavirus strain, India has suspended all passenger flights to and from Britain between December 23 and 31. Dozens of countries have clamped limited or comprehensive travel bans in a worldwide scramble to keep out the new coronavirus strain spreading fast across Britain. Travellers from the UK landing at any Indian airport before the flight ban kicks in at midnight Tuesday will have to undergo mandatory RT-PCR tests, based on which institutional quarantine for at least 14 days or monitored home isolation for a week will be advised, civil aviation minister HS Puri tweeted.
