President Donald Trump's travel ban on 26 European nations has come into force in the US, as part of a contingency plan to tackle the coronavirus crisis.
It affects countries that are members of the Schengen border-free travel area and excludes the UK, the Republic of Ireland and returning US citizens.
Mr Trump also declared a national emergency, freeing up to $50bn (£40bn) in relief funds.
There are nearly 2,000 confirmed cases of Covid-19 in the US, and 43 deaths.
