U.S. President Donald Trump said the United States is close to reaching a deal with Iran, but warned that Washington is prepared to achieve its objectives by other means if negotiations fail.

Axar.az reports that Trump made the remarks during a speech at the White House.

"We're close to maybe making a deal… I don't know. We're going to win one way or the other. Either we're going to make a deal, or we're going to finish the job," he noted.

"They will not have a nuclear weapon," Trump said, adding that the United States would secure what he described as enriched nuclear material, referring to it as "nuclear dust."
