Donald Trump says he wants to "suspend immigration from areas of the world where there is a proven history of terrorism."
It wasn't immediately clear whether Trump was proposing a change from his long-standing proposal to temporarily bar foreign Muslims entering the U.S.
The presumptive GOP presidential nominee also called on Muslims in the U.S. to work with law enforcement on finding potential attackers.
He made the proposal Monday in Manchester, New Hampshire, a day after the worst mass shooting in U.S. history in Orlando.
The presumptive Republican nominee called for an overhaul of the nation's immigration system and said that "we have to control our borders now — not later, now."
