Donald Trump has launched an attack on Angela Merkel stating that she has made a "huge mistake with the migrants".

Mr Trump made the claims during an interview with French media ahead of his victory in the New Hampshire primary.

He said: "What's happening in Europe can lead to its collapse. It's dramatic what (Merkel) has allowed to happen, this flood,"

He added: "My German friends no longer know where they are. They can't believe their eyes about what is happening…they're desperate."

Speaking about the attacks that took place in France on November 13, Trump said that the French should have been allowed to bear arms and defend themselves.

He added: "The only people who had weapons were the killers...it was 'open bar' for a massacre."

The pro-gun candidate went on to claim that the killers "were like kids in a candy store".

He added: "I always carry a weapon on me. If I'd been at the Bataclan or one of those bars, I would have opened fire. I would have perhaps died, but at least I would have taken a shot. The worst thing is the powerlessness to respond to those who want to kill you."
