US President Donald Trump says that the memorandum of understanding signed with Iran to end the conflict is “over”, adding he doesn’t want to engage with Tehran.

Trump was speaking in Ankara ahead of the Nato summit.

“To me, I think it’s over,” he said after a pause when asked about the ceasefire. “I don’t want to deal with them anymore; they’re scum … they’re led by sick people.”

He added, “I’ll speak to our negotiators, they want to negotiate … but they have to come back to me.”

Trump said, “Frankly, I don’t want to waste my time with them. Now, I’ll let our wonderful negotiators keep talking if they want, but I don’t see it.”

He added, “As far as I’m concerned, it’s just a waste of time dealing with them. They’re liars.”
