Republican presidential hopeful Donald Trump on Monday unveiled his anti-terrorism plan, saying he would implement "extreme vetting" of immigrants and suspend immigration from certain countries to protect the United States.
In a policy speech in the swing state of Ohio, the billionaire real estate mogul - who is vying with Hillary Clinton for the White House - vowed to "crush and destroy" the Islamic State in Iraq and Syria (ISIS) group, accusing Clinton and President Barack Obama of allowing it to grow.
He also pledged to launch a "commission on radical Islam" to root out extremist networks and stop radicalisation of young Americans.
"We should only admit into this country those who share our values and respect our people," Trump said.
"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."
Trump called for a "new approach" to fighting terror, slamming the policies put in place by Obama and Clinton, who served as his first secretary of state.
"Our current strategy of nation building and regime change is a proven absolute failure. We have created the vacuums that allow terrorism to grow and thrive," he said.
Trump said he would suspend immigration from "some of the most dangerous and volatile regions of the world, that have a history of exporting terrorism".
