PRAGUE — The Czech Republic has become another European Union country to ban all flights from Britain due to an outbreak of a new strain of the coronavirus in England.

The Health Ministry says the ban becomes effective on Monday.

Monday’s announcement comes after the country started to require all people arriving in the country who spent at least 24 hours on British territory in the last two weeks to isolate.

The same restrictive measure was imposed by neighboring Slovakia, starting on Monday.

European countries including the Netherlands, Austria, Italy and Bulgaria said they would halt flights from the U.K., hours after Britain’s government imposed tough new coronavirus restrictions on large areas of southern England to curb what officials described as a fast-moving new strain of the virus.
