Israeli PM Benjamin Netanyahu

After a grueling political marathon of negotiations, Iran and the P5+1 were reportedly close to striking a historic deal to end the Iran nuclear crisis. It is slated to be signed in Vienna on Monday, Israeli newspaper Yediot Ahronot reported.

Meanwhile, an Israeli security source warned against Iran's "tricks and shticks" that he said would surely follow the "inconceivably dangerous" deal.

"The West is leading problematic negotiations that will result in failure," said the source. "They have all the tools and capabilities to lead Iran down the correct path.

"Iran entered negotiations at a disadvantage, economically strangled and desperate for an agreement. Instead of pushing them further, leading to the total freeze of the nuclear program, without tricks and shticks, the West acted like amateurs and gave Iran a gift."

Defense Minister Moshe Ya'alon also criticized the impending deal, calling it a "historic mistake" filled with "unprecedented concessions."

According to Ya'alon, Saudi Arabia, Egypt and Turkey would all feel an urgent need to develop their own nuclear options as a result of the impending agreement.

French media reports cited one Iranian official claiming that 99 percent of the 100-page agreement had been completed, paving the way for the foreign ministers' signatures on Monday.

According to the official, negotiators had yet to agree on the expiration date of the agreement and precise dates to end sanctions on Iran.
