Countries around the world have been introducing new restrictions, and tweaking existing ones, on travel from Britain and elsewhere amid concerns about new coronavirus variants.

The restrictions focus mainly on the U.K., which imposed strict new lockdown measures over the weekend because of what it described as the unusually rapid spread of a new variant there. A few other European countries have confirmed cases of the variant, and another variant considered especially infectious has been identified in South Africa.

After a rush of uncoordinated travel restrictions European Union member states independently imposed since Saturday night, the European Commission said Tuesday people returning from the U.K. should be able to do so provided they test negative for the virus, or quarantine. It said that “cargo flows need to continue uninterrupted.”

Here is a look at restrictions currently in place:

France: Will start allowing EU citizens and British nationals with EU residency back from the U.K. as of midnight Tuesday, after previously banning all passenger and cargo traffic from Britain.
