In 1995, Mohammad Deif’s mentor, Yehya Ayyash, was killed. Deif learned the expertise of assembling IED’s (improvised explosive device) through Ayyash. Following Ayyash’s death, Deif assumed the role of becoming “the engineer” in the Ezzedeen al-Qassam Brigades, Hamas’ armed military wing. As a result, he became the mastermind behind a series of terrorist attacks that hit Tel Aviv and Jerusalem. In 2002, he took over as commander of the Ezzedeen al-Qassam Brigades. As to this day, Deif is held personally responsible for the deaths of dozens of civilians in suicide bombings since 1996. He is also considered to be the co-designer of the Qassam rocket.
In February 2006, some Israeli media outlets reported that Deif, unhappy with the truce announced by Hamas, decided to split from Hamas to join Al-Qaeda cells being established in the Gaza Strip. However, this move was denied by the Ezzadeen al-Qassam Brigades. In 2007, Deif led Hamas’ military wing to violently oust security forces loyal to Mahmoud Abbas from the Gaza Strip.
The following quotes are representative of the true nature of the leaders of Hamas:
“Today you have left the hell of Gaza in shame but have not gotten out completely, as you continue to occupy Palestine….We tell the Zionists who have tarnished our soil, we tell you that all of Palestine will become a hell” (NYT, August 28, 2005)
“The al-Qassam Brigades…are better prepared to continue on our exclusive path to which there is no alternative, and that is the path of jihad and the fight against the enemies of the Muslim nation and mankind….We say to our enemies: you are going on the path to extinction, and Palestine will remain ours including Al-Quds (Jerusalem), Al-Aqsa (mosque), its towns and villages from the (Mediterranean) Sea to the (Jordan) River, from its North to its South. You have no right to even an inch of it.”
