Trump dismisses leaked Iran pact details as fake news

A senior US official, speaking on condition of anonymity, said that under the agreement Iran's nuclear material, "will be destroyed and removed," and its nuclear programme will be dismantled.

Iran is believed to possess 900 pounds (408 kilograms) of highly enriched uranium.

"None of their money released until they perform. Strait of Hormuz will be open. No Iran funding of terrorist groups," the official said.

"This is what they have agreed to. This is a performance-based deal," the official said. Trump said on Thursday he was calling off new strikes on Iran because a deal had been reached.
