DUBAI/WASHINGTON — U.S. President Donald Trump said on Tuesday that the United States may need to attack Iran again, and he was only an hour away from deciding on a strike before he postponed the attack.

Trump was speaking to reporters at the White House a day after saying he had paused a planned resumption of attacks following a new peace proposal by Tehran.

"I was an hour away from making the decision to go today," Trump said on Tuesday.

He also said Iran's leaders are begging to make a deal, but that a new U.S. attack would happen in the coming days if one was not reached.
