US President Donald Trump said Wednesday that the US has had "very good talks" with Iran over the last 24 hours and "it's very possible we'll make a deal."

"They want to make a deal badly," Trump told reporters during an event in the Oval Office.

"We'll see if we get there. If we get there, they can't have nuclear weapons," he added.

When asked whether there was a deadline for a deal, Trump responded, "Never a deadline. It will happen."
