Countries around the world are racing to introduce travel bans and restrictions on southern African countries in an effort to contain a new variant of Covid-19, called Omicron.
The moves come after the variant was officially named by health officials.
Early evidence suggests Omicron has an increased re-infection risk, the World Health Organization (WHO) says.
Meanwhile, hundreds of passengers arriving in Amsterdam from South Africa were tested for the new variant. Some 61 people on two KLM flights tested positive for Covid-19 and have been quarantined at a hotel near the airport while they have further tests, Dutch officials said.
The Netherlands is currently struggling with a record-breaking surge in cases. An extended partial lockdown comes into force there on Sunday evening.
The new Omicron variant was first reported to the World Health Organization from South Africa on 24 November.
It has also been identified in Botswana, Belgium, Hong Kong and Israel.
More suspected cases were reported in Germany and the Czech Republic on Saturday. (BBC)
