Israel is waging a covert assassination campaign across the Middle East in an effort to stop its key enemies co-ordinating their activities.
Israeli agents have been targeting meetings between members of Hamas and the leadership of the militant Hezbollah group, and the Iranian Revolutionary Guards.
Under the current Mossad chief, Meir Dagan, Israel is believed to have renewed efforts to kill high-level opponents. Only months after the former paratrooper assumed leadership of the intelligence service in October 2002, senior Hezbollah operatives in Lebanon began to be targeted. He was credited with ordering the killing of two relatively senior Hezbollah members who were killed in southern Beirut in July 2003 and August 2004.
