With coronavirus being declared a pandemic by the World Health Organization (WHO), Donald Trump ramped up measures to tackle the illness.
The president said on Wednesday night he was suspending all travel between the US and Schengen area free movement zones of Europe – which excludes the UK and Ireland – for 30 days starting on Friday as he seeks to combat Covid-19.
Trump made the announcement in an Oval Office address to the nation, blaming the EU for not acting quickly enough to address the outbreak of the virus and saying US clusters were "seeded" by European travellers.
He said "we are marshalling the full power" of the government and private sector to protect the American people.
The EU condemned the travel ban, hitting out at the "unilateral" decision taken "without consultation”.
However, the US is not the only country in the world to implement travel restrictions since the coronavirus crisis started.
