France has added UK, Colombia, Costa Rica and Uruguay to its list of countries deemed as COVID-19 high-risk.
This means people arriving from these countries will have to undergo COVID-19 safety measures such as quarantining on arrival.
The French Prime Minister's department added that these measures will take effect from May 16.
It's part of efforts by the country to ensure its third wave of the virus recedes.
In April, France had put Brazil, Chile, Argentina, South Africa and India on its list of COVID high-risk countries, requiring people arriving from those countries to undergo a 10-day quarantine upon arrival.
