Donald Trump has suggested terror attacks in France and Germany were their "own fault" and citizens of the countries could now be subject to "extreme vetting" entering the United States.

Mr Trump said the two European nations had been "totally compromised by terrorism" because they had "allowed people in".

The Republican presidential nominee, who has threatened to introduce punitive import taxes, also said America could pull out of the World Trade Organisation if he is president.

He said: "We'll renegotiate or pull out. These trade deals are a disaster. The World Trade Organisation is a disaster."

When asked if his "extreme vetting" policy might lead to "a lot of people from overseas" not being allowed in the Republican presidential nominee said: “Maybe we get to that point."
