Muhammad Suleiman, a top aide to the Syrian president, was shot in the head and neck, and the Israeli military team escaped by sea.

While Israel has never spoken about its involvement, secret U.S. intelligence files confirm that Israeli special operations forces assassinated the general while he vacationed at his luxury villa on the Syrian coast.

The internal National Security Agency document, provided by former NSA contractor Edward Snowden, is the first official confirmation that the assassination of Suleiman was an Israeli military operation, and ends speculation that an internal dispute within the Syrian government led to his death.

A top-secret entry in the NSA's internal version of Wikipedia, called Intellipedia, described the assassination by "Israeli naval commandos" near the port town of Tartus as the "first known instance of Israel targeting a legitimate government official."
