broken the truce. The continuing rocket fire into Israel led to the Gaza War (2008–09) in late December 2008. Armed strength Since its establishment in December 1987, the military capability of the Brigades has increased markedly, from rifles to Qassam rockets and more. The Brigades have a substantial inventory of light automatic weapons and grenades, improvised rockets, mortars, bombs, suicide belts, and explosives. The group engages in military-style training, including training that takes place in Gaza itself on a range of weapons designed to inflict significant casualties on civilian and military targets. The Brigades also have a variety of anti-tank guided missiles including the Kornet-E, Konkurs-M, Bulsae-2 (North Korean version of Fagot), 9K11 Malyutka and MILAN missiles, as well as shoulder-launched anti-aircraft missiles (MANPADS), such as the SA-7B, SA-18 Igla missiles, and it is believed a number of SA-24 Igla-S that it received from Libya. While the number of members is known only to the Brigades leadership, in 2011 Israel estimated that the Brigades have a cadre of several hundred members who receive military-style training, including training in Iran and Syria. Additionally, the Brigades have an estimated 30,000 operatives "of varying degrees of skill and professionalism" who are members of the internal security forces, Hamas, and their supporters. These operatives can be expected to reinforce the Brigades in an "emergency situation." Other sources estimate their strength at 30,000-50,000. According to a statement by CIA director George Tenet in 2000 possibly referring to the Brigades, Hamas has pursued a capability to conduct attacks with toxic chemicals. There have been reports of Hamas operatives planning and preparing attacks incorporating chemicals. In one case, nails and bolts packed into explosives detonated by a Hamas suicide bomber in a December 2001 attack in the Ben-Yehuda street in Jerusalem were soaked in rat poison. In 2014 they launched the first Palestinian reconnaissance (UAV) aircraft called Ababeel1. List of the Brigades' attacks against Israeli targets Leaders killed by Israel or other causes On 5 January 1996, Israel's Shin Bet arranged for a cell phone that was both bugged and contained explosives be given to Yahya Ayyash. When it was confirmed that it was Ayyash on the phone, Shin Bet remotely detonated it, killing Ayyash instantly. On 3 September 2005, after Israel's withdrawal from settlements in the Gaza Strip, the Al-Qassam Brigrades revealed for the first time the names and functions of its commanders on its website
