Prime Minister Benjamin Netanyahu said Sunday that "world powers and Iran are galloping toward an agreement that will allow Iran to arm itself with nuclear weapons that will endanger the existence of the state of Israel," adding that he would do everything in his power to foil such an accord before the March 31 deadline.

Meanwhile, Iranian Foreign Minister Mohammed Javad Zarif said Sunday that Israel cannot hide atrocities against Palestinians and others using an excuse of a hypothetical Iranian threat.

Speaking in Munich, Zarif also said he doesn't believe another extension is in anybody's interest: "This is the opportunity to do it, and we need to seize this opportunity," he said. "It may not be repeated." Nevertheless, he added, it would not be the end of the world if an agreement was not reached.

Zarif also said that Iran is prepared to engage with Saudi Arabia, Turkey and Egypt. Zarif met Sunday with U.S. Secretary of State John Kerry for the second time in days, as world powers and the Islamic Republic attempted to reach an accord on the latter's contentious nuclear program.

Also Sunday, Iranian Supreme Leader Ayatollah Ali Khamenei said that he would go along with any nuclear deal with the six major powers if it did not go against the interests of his nation.

"I would go along with the agreement in the making," Khamenei said in a speech to air force personnel, as quoted by the official news agency IRNA, alluding to ongoing negotiations to reach a pact that would curb Iran's disputed nuclear work in return for a phased lifting of sanctions imposed on Tehran.

"Our (nuclear) negotiators are trying to take the weapon of sanctions away from the enemy. If they can, so much the better. If they fail, everyone should know there are many ways at our disposal to dull this weapon," he said.
