President Obama has said the United States will apply the toughest possible sanctions against Iran over an alleged plot to kill the Saudi Arabian ambassador to Washington. Mr Obama said America had evidence to show the world that Iran had behaved dangerously and recklessly.
"One of the principles of international behaviour is that our diplomats - we send them around the world - that they are going to be protected, they are not targets for threats or physical violence. And for Iran to have been involved in a plot like this indicates the degree to which it has been outside of accepted norms of international behaviour for far too long."
Mr Obama said Washington was considering all options in deciding how to respond. Tehran has already dismissed the suggestions of an Iranian plot.

The head of the international environmental group Greenpeace has been banned from entering Indonesia, where it's been campaigning against deforestation.
