US Republican presidential front-runner Donald Trump has blamed organised "thugs" for protests and violent scuffles that shut down his Chicago rally and said the incident had "energised America."

Trump, who is currently at a campaign rally in Dayton, Ohio, cancelled the Chicago event yesterday after it turned chaotic, with scuffles breaking out between protesters and backers of the real estate magnate.

The Celebrity Apprentice star tweeted:

The First Amendment to the US Constitution protects freedom of speech and assembly.

The Chicago rally came ahead of five primary elections on Tuesday, including contests in Ohio and Illinois.

Trump has drawn fervent support as well as criticism for his calls to build a wall along the US-Mexico border and to impose a temporary ban on Muslims entering the country.

His rallies often attract small groups of protesters, but Friday's was the first at which there may have been as many protesters as supporters.

Asked by CNN interviewer Don Lemon if he would take back anything he had said, Trump said: "Now, getting back to before tonight, when I talked about illegal immigration, I have no regrets whatsoever."

"If I didn't bring up illegal immigration, it wouldn't even be a subject of the campaign," he added.

At the University of Illinois-Chicago stadium rally the two sides shouted at each other until a Trump staffer appeared and said the event would be put off until an unspecified date for security reasons.

Police said five people were arrested, including CBS News reporter Sopan Deb. Two officers were injured, with one requiring stitches, police said.

The cancellation followed an appearance by Trump in St Louis on Friday during which protests forced him to halt his speech repeatedly.

In statements, Republican rival candidates Ted Cruz and Marco Rubio both called the incident "sad" and said the protesters should have let the rally happen.

Trump has a significant lead in primary contests over the three remaining Republicans vying for the White House. He is looking to cement it on Tuesday.

Ohio Governor John Kasich, also battling Trump for the Republican presidential nomination, told reporters before a campaign event in Cincinnati that Trump had "created a toxic environment."

"And that toxic environment has allowed his supporters, and those who seek confrontation, to come together in violence."
