Benjamin Netanyahu addressed the General Assembly as he seeks to repair relations with President Barack Obama, damaged by the Iran deal and the Israeli leader's rejection, while seeking re-election, of a two-state solution.
He held up a book by Iran's supreme leader Ayatollah Ali Khamenei, calling it a detailed plan for the destruction of Israel, and saying that he had vowed Israel would not exist in 25 years' time.
"Utter silence. Deafening silence," added Netanyahu, before falling silent for 45 seconds from the rostrum. Not a sound could be heard from the vast General Assembly chamber until he resumed speaking.
"Perhaps you can understand why Israel is not joining you in celebrating this deal," he said.

Netanyahu is fond of gimmicks. Three years ago at the UN, he made headlines with a cartoon of an Iranian bomb and by drawing a line on it.
On the decades-old conflict with the Palestinians, he said he was prepared to "immediately resume direct peace negotiations" without preconditions, although the Palestinians condition a resumption of dialog on an end to settlement building and the release of prisoners.
"Israel expects the Palestinian Authority to abide by its commitments. The Palestinians should not walk away from peace," he said.
Palestinian leader Mahmud Abbas told the Assembly yesterday that Israel's refusal to release prisoners and stop settlement activity, meant that Palestinians could not be bound by past agreements.
"But we owe it to our peoples to try. To continue to try. Because together... If we actually sit down and try to resolve this conflict between us... We can do remarkable things for our people."
His remarks come with Netanyahu scheduled to speak with Obama at the White House in November -- their first meeting after a deep row about the Iranian nuclear deal.
