That fortress-like structure is the Israeli Institute for Biological Research (IIBR) where Israel develops its biological and chemical weapons and prepares for any eventuality of biological or chemical warfare. It is the most top-secret military installation in Israel. So tightly is it guarded by military censorship that the Israeli press has to turn to Western sources for scraps of information made available to them, very intermittently, by special contacts inside the institute.
The IIBR is staffed by some 300 scientists and technicians employed in one or more of its many departments, each of which specialises in a specific area of chemical or biological research generally aimed at the production of chemical or biological weaponry. One of these departments, for example, is reported to have developed the poison that was used by the notorious Mossad assassination unit, Kidon, in its botched attempt to eliminate Hamas politburo chief Khaled Meshaal in 1997. Nevertheless, if there remains some question over the accuracy of this information, which was reported in Haaretz, no one disputes that the first time the institute’s products were used in an assassination operation was in late 1977 when then prime minister Menachem Begin ordered Mossad to eliminate Wadie Haddad.
It is not unlikely that Mossad conducted many assassination operations in this way, so as not to leave its fingerprints. In other words, the seemingly accidental deaths of many individuals that Israel regarded as a threat may have actually been caused by substances produced by IIBR. Most likely, the poison that Mossad agents injected into Hamas leader Mahmoud Al-Mabhouh in Dubai in February 2010 came from IIBR.
