The USA has increased the number of countries affected by its travel ban. North Korea, Venezuela and Chad are now facing the same restrictions as Yemen, Iran, Libya, Syria and Somalia.
Sudan has been removed from the list and Iraqi citizens will be allowed to visit America but under "additional scrutiny."
While most of the countries on the list face full bans with no end-date given, the Venezuelan ban only applies to government officials.
President Donald Trump made the declaration on Sunday, claiming on Twitter: "Making America safe is my number one priority. We will not admit those into our country we cannot safely vet."
Trump’s repeated attempts to ban certain nationalities from travelling to America have been controversial because they target largely Muslim countries.
In a press release issued by the White House press secretary, failure to share information and help identify security risks is cited among reasons for the ban for each of the countries listed.
