美國政府官員和西方國家外交人員說，美國等西方國家正考慮對伊朗發(fā)起針對性制裁、而非打擊面較大的廣泛制裁，以向伊朗政府施壓、打破核談僵局。

The US government is readying sanctions against parts of the Iranian government.

It includes those involved in the deadly crackdown on Iranian protesters, marking a shift to a more aggressive US stance against the Islamic republic.

The Washington Post reported that sanctions are still being decided but they need to be carefully targeted to avoid alienating the Iranian public. High on the list of targets is the Iranian Revolutionary Guard.

US officials said the increasingly central role of the Corps in both the economy and protests makes it a target of resentment for the Iranian public, and for tough US sanctions.

The officials also said the aim of any sanctions will be to force the Tehran government to the negotiating table, rather than to punish it.
