The reactor complex was heavily damaged, according to plan. Eleven men — ten Iraqi soldiers and one French civilian researcher — were killed in the attack. Since that time, it has been proposed by some commentators that the French researcher, Damien Chaussepied, was actually a Mossad agent who was responsible for placing homing beacons on site for the aircraft to follow, although no incontrovertible evidence for this has yet been presented.

Although almost out of fuel, all fourteen jets returned to Israeli territory and landed safely.
