Chemical/Biological weapons: Beyond nuclear weapons, Israel is long believed to have biological and chemical weapons as well as the means to deliver them, primarily the Jericho missile.
Research and weaponization: A 1989 Defense Intelligence Agency report, obtained by the Natural Resources Defense Council, reported that Israel's Jericho missiles could carry high explosive or chemical warheads as well as nuclear. The country's leading chemical and biological warfare facility is at Nes Zionyaa, outside Tel Aviv. The Israeli Institute for Bio-Technology is believed to be the home of both offensive and defensive research.
