In 1992 an Israeli cargo plane crashed in Amsterdam killing forty-three people. The Israelis claimed it was carrying flowers and perfume. It took six years and a Dutch parliamentary enquiry before they admitted it was carrying DMMP, a key component for sarin nerve gas. The DMMP was bound for The Israeli Institute of Biological Research at Nes Ziona, one of Israel's most secret defence sites. It is subject to no international inspection and reporting of its activities in Israel is prevented by strict military censorship.
