Trump says US and Tehran having 'good, friendly talks'

President Donald Trump said on Monday that the US was having "good talks" with Iran and there was a chance of a deal over their conflict, but warned US strikes would resume if the negotiations failed to deliver.

Washington abruptly suspended a two-week campaign of air strikes against Iran on Saturday in the president's latest strategic U-turn in the five-month-old conflict.

"We're talking right now," Trump told reporters aboard Air Force One. "We're having good talks... I think there's a good chance that something could happen, and if it does, good, if it doesn't, we go back to doing what we were doing two days ago."

At a rally in Michigan, he added: "You can't bribe them. You've got to beat them, and we'll beat the hell out of them. But we'll see how it turns out. Right now, there are very friendly negotiations going on."

In contrast to the president's remarks, Saudi Arabia, Jordan and Iraq reported drone attacks on Monday.

Saudi Arabia said it shot down drones launched from Iraq by Iran-backed armed groups, and it reserved the right to respond.
