US airports have been thrown into chaos as new coronavirus health screening measures for people returning from Europe come into force.

Long queues formed as travellers waited for hours for the screenings before passing through customs.

Earlier, Vice-President Mike Pence said a ban imposed on travel from European nations would be extended to the UK and Ireland on Tuesday.

The US has more than 2,700 confirmed cases, with 54 deaths.

Correspondents say there is a growing sense of unease and confusion in the US, with fears of a run on hospital beds and concern about childcare as tens of millions of students are sent home from school.
