Mohammed Zuhair Siddiq also known as Mohamad Zouhair Siddik is another self proclaimed former Syrian intelligence operative who used to live in Lebanon.
Following the Assisination of Former Lebanese prime minister Rafik El Hariri, Muhammad Zuhair Siddiq told the IIIC that the first stages of planning for the assassination were carried out in clandestine meetings between senior Lebanese and Syrian officers from July to December 2004 at his apartment in Khaldeh and later at an apartment in southern Beirut.
Mohammed Zuhair claimed to visited a Syrian military camp located in Zabadane, where he saw the Mitsubishi van being filled with explosives. Zuhair added that Abu Adas had been forced to make the videotape at gunpoint, before being killed by the Syrians and placed in the Mitsubishi van. According to Siddiq, the actual suicide bomber was an Iraqi duped by the Syrians into believing that the targeted motorcade belonged to an Iraqi Prime Minister Ayad Allawi who had just visited Lebanon at that time.
Husam Taher Husam another self proclaimed former Syrian intelligence operative and Mohammed Zuhair Siddiq provided sufficient information for the Lebanese authorities to arrest the four generals.
Both Husam and Siddiq testimonies were used as the basis for the IIIC’s conclusion that there is evidence pointing at both Lebanese and Syrian involvement in the Hariri assassination.
