Republican presidential nominee Donald Trump says he will institute "extreme vetting" of immigrants and establish a new "commission on radical Islam" if he wins the US election in November.
In a foreign policy speech on Monday, the billionaire businessman said the goal of the new commission would be to "expose" networks within the US "that support radicalisation".
As president, Trump said, he would ask the state department and department of homeland security to identify regions of the world that remain hostile to the US and where screening might not be sufficient to catch those who pose a threat.
"We should only admit into our country those who share our values and respect our people," he said from Youngstown, Ohio.
"In the Cold War, we had an ideological screening test. The time is overdue to develop a new screening test for the threats we face today. I call it extreme vetting."
As part of his plan, Trump, who has issued calls for a ban on Muslims entering the US, said that he would "temporarily suspend immigration" from countries that have a history of "exporting terrorism".
He said that every year, the US admits 100,000 permanent immigrants "from the Middle East", and hundreds of thousands more temporary workers and visitors from the same region.
"We will stop processing visas from those areas until such time as it is deemed safe to resume based on new circumstances or new procedures."
Fight against ISIL
Outlining his policy to fight the Islamic State of Iraq and the Levant (ISIL), the Republican nominee also reversed an earlier position, promising to would work with NATO allies to defeat the armed group if elected president.
"We will also work closely with NATO on this new mission," said Trump, whose previous remarks about the organisation earlier this summer drew heavy criticism from US allies, and even some of his fellow Republicans.
Trump also accused his Democratic opponent Hillary Clinton of enabling the rise of ISIL, also known as ISIS.
He also attacked her record as secretary of state and said she lacked the judgment and character to lead the country.
