The proposal would require an act of Congress, as under US law it's illegal to try US citizens at military commissions, The Herald noted.

"I would say they could be tried there, that would be fine," Trump told the newspaper in an interview.

"I know that they want to try them in our regular court systems, and I don't like that at all. I don't like that at all."

Trump has previously criticized President Barack Obama's efforts to close the Guantánamo Bay detention camp.

"I want to make sure that if we have radical Islamic terrorists, we have a very safe place to keep them," Trump said. He said Obama, meanwhile, was "allowing people to get out that are terrible people."
