June 17 (UPI) -- President Donald Trump said Wednesday at a press conference in France that if Iran doesn't abide by the memorandum of understanding, the United States may bomb the country.

The press conference lasted more than an hour, with Secretary of State Marco Rubio and Commerce Secretary Howard Lutnick standing behind him.

Trump made the remark in his opening statement.

"If they don't honor that, we'll probably go back to bombing them until they honor it, you know?" he said. "It's amazing what bombs can do."
