Former Mossad chief and national security adviser Ephraim Halevy was quoted by the New York Times on Thursday saying that if he were Iranian he "would be very fearful of the next 12 weeks".

Halevy also told Israel Radio on Thursday that if the Iranians "continue to play their games" in nuclear talks with world powers, they would be underestimating Israel's resolve.

"[The Iranians'] math is off if they think they have open-ended immunity" in these talks, he said.
