The European Union recommended on Monday that its 27 nations reinstate restrictions on tourists from the US because of rising coronavirus infections there.
The decision by the European Council to remove the US from a safe list of countries for nonessential travel reverses advice that it gave in June, when the bloc recommended lifting restrictions on US travellers before the summer tourism season.
The guidance is nonbinding, however, and US travellers should expect a mishmash of travel rules across the continent.
The EU has no unified Covid-19 tourism policy and national EU Governments have the authority to decide whether they keep their borders open to US tourists.
The EU also removed Israel, Kosovo, Lebanon, Montenegro and North Macedonia from the safe travel list.
The United States has yet to reopen its own borders to EU tourists, despite calls from the bloc for the Biden administration to lift its ban.
The European Council updates the safe travel list based on criteria relating to coronavirus infection levels. It gets reviewed every two weeks. The threshold for being on the EU list is having not more than 75 new COVID-19 cases per 100,000 inhabitants over the last 14 days.
