In an 11th-hour escalation of his lobbying against an expected nuclear deal between Iran and six world powers, Israeli Prime Minister Benjamin Netanyahu turned to the Iranian public on Monday with a new Farsi-language Twitter account.
An Israeli official said Netanyahu aimed to persuade ordinary Iranians they stood to lose from a deal that limits, but does not eliminate, Tehran's nuclear programme because "the more the regime feels strong and impervious to foreign pressure, the more it increases domestic oppression".
Israel, not a party to the negotiations with Iran, has tried with little effect to get the terms imposed on its arch-foe toughened up. The talks, held in Vienna, appeared close to yielding a deal ahead of a midnight deadline.
Tweets posted on Netanyahu's new account, @IsraeliPM_Farsi, restated his argument that such a deal would "pave the way for Iran to get nuclear bombs and billions of dollars for terrorism" and that the Iranian leadership should not be engaged diplomatically while it orchestrates anti-US "hate marches" on the streets of Tehran.
Some Farsi-fluent Twitter users were unimpressed.
One spotted a syntax error in the account. Another suggested Netanyahu might be better off "explaining with a crude cartoon" - a reference to an illustration the Israeli prime minister held up during a UN speech in 2012 to show how close Iran, which insists its nuclear projects are peaceful, was to making a bomb.
