Iran live updates: Trump insists US has 'massive amounts' of munitions

In an interview with Fox 5 after delivering on-stage remarks in Las Vegas on Wednesday night, President Donald Trump again said negotiations with Iran appear to be "working out quite well."

However, he warned "you never know" what could happen and cautioned that "it may be, it may not be" different from previous rounds of talks.

The president said that Iran was influenced by the severity of strikes he was threatening last week. He added that such an attack is still on the table, saying, "We are ready to go."

President Donald Trump stressed during remarks in Las Vegas on Wednesday that the U.S. and Iran "are talking" and emphasized his desire to continue diplomatic relations while also repeating threats of deadly escalation.

"I'd rather make a deal because I don't want to kill people. I do not want to kill people," he said, going on to say, "We were all set for the biggest attack since World War II. And they called me and they said, 'Please don't do it, let's talk.'"

"But we are talking. Let's see what happens. But they respect us," he continued.

Trump again promised that as soon as the war ends, prices would come down on oil and gas -- before moments later saying "we may have to send it up again," seeming to allude to potential renewed military action against Iran.

Israeli Ambassador Yechiel Leiter asked the Americans to stop the talks between Israel and Lebanon in Rome three hours early because the ambassador was frustrated over repeated inaccurate leaks from the Lebanese delegation, two sources familiar with the talks told ABC News.

Talks between Israel and Lebanon ended early on Wednesday due to events on the ground, but will reconvene Thursday morning, according to a State Department official.

Discussions focused on a range of political and military issues and were extremely productive, the official said. The technical teams made progress on determining key details on implementation of the Trilateral Framework.
