The US will impose "major" additional sanctions on Iran in a bid to prevent the country obtaining nuclear weapons, President Donald Trump says.
He said economic pressure would be maintained unless the leadership in Tehran changed course."We're putting additional sanctions on," he told reporters. "In [some] cases we are moving rapidly."
It comes after Iran announced it would exceed internationally agreed limits on its nuclear programme.
Iran's economy is suffering badly and it is threatening to breach some of the terms of the nuclear agreement it reached with the major powers.
