Just two days before U.S.-Iran nuclear negotiations were set to begin, Israel assassinated the high-ranking Iranian official leading the talks, putting the breakthrough deal at risk.
Ali Shamkhani was one of several Iranian officials killed in Israel's surprise attack early Friday morning. Shamkhani served as a close aide to Iranian Supreme Leader Ayatollah Ali Khamenei and was responsible for securing an agreement that restored diplomatic ties between Iran and Saudi Arabia, CNN reported.
