His nickname was 'Engineer', because he was so smart, like an engineer.
He committed many attacks against Jews. Because he was so smart, Mossad was not able to catch or kill him. Finally Mossad found a way. Engineer was given a cellphone by an undercovered Mossad agent. When he was on a call, Mossad detonated the explosive hidden inside the cellphone battery.
The amount of explosive was very small. But since the phone was next to his ear, he got killed.
