(WAM) — France is closing its borders to people arriving from outside the European Union starting Sunday to try to stop the spread of new variants of the coronavirus and to avoid a third lockdown.

French Prime Minister Jean Castex announced the measure Friday night after an emergency government health security meeting at the presidential palace, warning of a “great risk” from the new variants, FRANCE 24 reported.

All those arriving from other EU countries will be required to produce a negative virus test, he said. France will also close all large shopping centres starting Sunday and limit travel to and from its overseas territories.
