“For months, Israeli and American intelligence agencies — including the CIA — had been secretly watching Iran’s Ayatollah Ali Khamenei for just the right moment,” CNN reports.“They were monitoring for his daily patterns — where he lived, who he met with, how he communicated and where he might retreat under threat of attack… They were keeping tabs, too, on Iran’s senior political and military leaders, who rarely gathered in the same place with the ayatollah, the country’s supreme leader for nearly four decades.”“Over the last several days, they found their opportunity. Top Iranian officials, including Khamenei, planned to meet Saturday morning at separate sites on a Tehran compound that is home to the offices of the ayatollah, the Iranian presidency and the national security apparatus.”“The overly cautious supreme leader felt less vulnerable during daylight hours, an Israeli source said, and let down his guard.”
