US expands sanctions on Iran, targeting oil and media
The US has tightened existing sanctions on Iran, in an effort to push Tehran to abandon its alleged nuclear weapons programme.
The measures further restrict Iran's access to its own oil revenues but also include financial restrictions against Iran's state-run media.
The sanctions are coming into effect under the terms of a bill passed by Congress six months ago.
International talks on Iran's nuclear programme are due later this month.
