While at the Islamic University of Gaza , Jabari joined Fatah , which advocated armed struggle against Israel . In 1982 , he was arrested by the Israeli authorities and imprisoned for 13 years . After being released he joined Fatah 's Islamist rival Hamas ' militant wing and was believed to have been involved in the bombing of a bus in Kfar Darom , following which he was arrested by the Preventive Security Force of the Palestinian Authority in 1998 , being released the following year . In 2002 , Jabari became the acting operational head of Hamas ' military wing when Mohammad Deif was seriously wounded in an Israeli airstrike . In this position Jabari was also a high-ranking official within Hamas ' political leadership , as well as the founder of the Nur Association , which aimed to help " martyrs and prisoners . " The Israeli Air Force and Shin Bet conducted a targeted precision air strike on 14 November 2012 , a part of Operation Pillar of Defense , killing Jabari while he was travelling in a car . The decision to liquidate him , according to Haaretz analyst , Reuven Pedatzur , arose from a decision by Israeli military to attack Hamas rather than seek a ceasefire . Jabari was the highest-level Hamas official killed in Gaza since the 2008 Gaza War
