A Fianna Fáil TD has said that the decision by US President Donald Trump to add Ireland and the UK to the travel ban, introduced to limit the spread of Covid-19, was "necessary".
The restrictions will come into force from 4am on Tuesday morning Irish time.
Under the restrictions, American citizens, Green Card holders and others are still allowed to return home to the US – but will be funnelled to 13 airports and be subjected to health screenings and quarantine orders, according to reports.
US Vice President Mike Pence said there had been a “unanimous recommendation” from health experts to extend the travel ban.
“In our taskforce meeting today the president has made a decision to suspend all travel to the UK and Ireland, effective midnight Monday night, eastern standard time,” Mr Pence announced yesterday.
Anyone not resident in the United States flying from Britain, Ireland, or any Schengen-area state will be turned away.
Niall Collins, Fianna Fáil's spokesman on foreign affairs, says it is a drastic step for a drastic moment.
"We live in exceptional times, which is completely unprecedented and I think the travel ban, whilst it is extreme, I think it is necessary," Mr Collins said.
