Asked about the ceasefire between the US and Iran, Donald Trump says: "I think it's over."
He tells reporters at the Nato summit: "I don't want to deal with them anymore, they're scum," reports BBC.
"As far as I'm concerned, it's over," he adds. "It's just a waste of time dealing with them, they're liars."
Trump says negotiators from both sides "can talk" but are "wasting their time".
