The months of preparation for the US-Israeli effort to assassinate Iran's top leader

Contrary to expectations, the incident that murdered Iran's Supreme Leader Ayatollah Ali Khamenei occurred in the middle of the morning rather than the middle of the night.

This was due to the US and Israel's decision to exploit a critical piece of information that had been received just hours earlier.

They had been waiting months for a chance to meet with high-ranking Iranian officials, and they found out that Khamenei would be at a complex in the heart of Tehran on Saturday morning.

They also knew where other high-ranking military and intelligence officials would be meeting simultaneously.

The US and Israel had been monitoring the supreme leader's travels for months. Although US President Donald Trump alluded to them in a social media post, the precise techniques they employed are unknown. He could not evade our highly advanced tracking systems and intelligence."

This could have been a human source reporting back, but it is more likely that Iranian people were being tracked technically.
