Europe condemns the U.S. travel ban as more nations add restrictions.

On both sides of the Atlantic on Thursday, the consequences of President Trump’s decision to ban most travel from Europe began to be felt economically, politically and socially.

European Union leaders issued a scathing statement condemning the move even as many nations on the Continent moved to tighten their own restrictions on the movement of people both within their borders and from outside.

“The coronavirus is a global crisis, not limited to any continent and it requires cooperation rather than unilateral action,” it said. “The European Union disapproves of the fact that the U.S. decision to impose a travel ban was taken unilaterally and without consultation.”

Tens of thousands of Americans in Europe scrambled to figure out what they needed to do before the 30-day travel ban goes into effect on Friday, with many unclear on the scope of the ban and worried that their flights home would be canceled. And airlines, hotels and scores of other industries — many of which had already been hurting from restrictions put in place to slow the spread of the virus — braced for even steeper declines.

Italy, already on lockdown, clamped down even further, and on Thursday morning virtually the only public places still open to its 60 million citizens were supermarkets and medical facilities.

Within the European Union — where the free movement of people among members states has long been considered one of the crowning achievements of the post-World War II order — the Czech Republic on Thursday joined other nations in announcing new border checkpoints.

Outside Europe, the fight against the virus also gained intensity, with India joining the growing list of countries imposing drastic travel limits.
