More on the US-Canada border closurepublished at 14:53 Greenwich Mean Time 18 March 2020
Earlier we reported President Trump's announcement that the US-Canada border will be closed to "non-essential traffic".
More details of when and how the closure will come into effect have yet to be announced.
But the move marks a drastic change in tone from earlier moves by the US and Canada to curb the spread of coronavirus across the world's longest land border between two countries.
Last Friday, a spokesperson for the US customs and border agency had denied any such closure was taking place.
And on Monday, Canadian Prime Minister Justin Trudeau announced that Americans would be exempt from the closure of Canada's borders to non-citizens. That now appears to have changed.
The US has yet to impose a worldwide ban, but the list of black-listed countries is continuing to grow.
As it stands, all foreign nationals from China, Iran and more than 25 European countries - including the UK - are unable to enter the US. This includes anyone who visited any of these countries within the 14 days before their trip to the US.
