Israeli Prime Minister Benjamin Netanyahu has called on world leaders to beware of a nuclear-armed Iran that according to him will be, "a thousand times more dangerous and more destructive" than the Islamic State (Isis) militant group.

Netanyahu's warning comes as world leaders will reconvene in Vienna prior to the 30 June deadline set to reach a nuclear deal with Iran.

"I see no reason to rush to a deal and certainly not a bad deal that paves Iran's path to the bomb, but also fills Iran's coffers with tens of billions of dollars to pursue its aggression throughout the Middle East and around Israel's borders," Netanyahu told Senator Bill Cassidy of Louisiana, reported AFP News.

"As we are meeting, the P5+1 talks are reconvening, and I'm afraid they're rushing to what I consider is a very bad deal.

"As horrific as Isis is, once Iran, the pre-eminent terrorist state of our time, acquires nuclear weapons, it will be a hundred times more dangerous, a thousand times more dangerous and more destructive than Isis."

US and Israel - Love and hate relationship

Netanyahu has hailed the relationship between the US and Israel as a "precious asset for both countries" during his meeting with the US Senator Cassidy on 26 May.

He urged Cassidy to prevent a nuclear deal agreement that can work against the world leaders, including the US and Israel.

"We shouldn't give Iran a path to nuclear weapons and billions of dollars to pursue aggression because of Isis," said Netanyahu. "Isis should be fought; Iran should be stopped."

Earlier, Netanyahu had cited a "profound disagreement" with US President Barack Obama over efforts by the world leaders to resolve the Iranian nuclear issue.

"We do have today a profound disagreement with the United States administration and the rest of the P5+1 over the offer that has been made to Iran," said Netanyahu.

"This is a regime, Iran, that is openly committed to Israel's destruction. It would be able, under this deal, to break out to a nuclear weapon in a short time, and within a few years, to have the industrial capability to produce many nuclear bombs for the goal of our destruction."

Britain, China, France, Russia, Germany and the US have been in talks with Iran to try to prevent Tehran's attempt at developing a nuclear bomb by offering to ease economic sanctions in return.

A 30 June deadline has been set for Iran and the P5+1 world leaders to reach a final nuclear deal.
