The US State Department has advised Americans to avoid all travel to France over rising coronavirus cases in the country, reports RTL.
France is battling a fourth wave of the virus even though Covid-19 hospitalizations are still way off previous highs.
The State Department issued a "Level 4: Do Not Travel" advisory for France on Monday, based on a parallel warning from the US Centers for Disease Control, the country's top medical body.
"If you must travel to France, make sure you are fully vaccinated before travel," the CDC said.
France has recorded more than 6 million cases and 111,000 deaths in total, and daily cases have crept back up to around 20,000 a day while deaths remain low compared to the height of the pandemic.
