Richard Silverstein, an American journalist and blogger on Israeli affairs, says he has been given a leaked document which outlines a plan for an Israeli attack on Iran's nuclear facilities.

He describes the document as a briefing memo that is being used by Prime Minister Netanyahu to show ministers that an attack on Iran would go "smoothly" and wipe out key infrastructure with a minimum of Israeli casualties.

Silverstein says the document was leaked by an officer in the army, senior members of which he says oppose attacking Iran. He says the officer received the document from a former senior minister in a former government.

Silverstein says the document does not mention any possible Iranian response to an attack.

Richard Silverstein spoke to Newshour on the BBC World Service.
