every peace plan must be discussed directly between Israel and the Palestinians, and to make this possible, the Palestinian Authority must put an end to terror, the horrifying expression of which we witnessed just last night in Netanya." Israeli retaliation The attack was perceived in Israel as the high point of a bloody month in which more than 135 Israelis, mostly civilians, were killed in terror attacks. Following the Passover massacre attack the Israeli government declared a state of emergency, ordered the immediate recruitment of 20,000 reservists in an emergency call-up, and in the following day launched the large-scale counter-terrorism operation Operation Defensive Shield in the West Bank which took place between 29 March and 10 May. Qeis Adwan, head of the suicide bombing network responsible for the massacre, was killed by IDF forces on 5 April 2002 during Operation Defensive Shield, after the IDF and the Yamam caught him in Tubas, some 70 kilometers north of Jerusalem. An armored IDF Caterpillar D9 bulldozer toppled the house where he was hiding, after he was given a chance to surrender and refused. Arrests and killings of perpetrators One of the two chief planners of the attack, Qais Adwan, a Hamas member who was involved in numerous attacks in which a total of 77 people were killed, was killed in a shootout with the IDF during Operation Defensive Shield. In May 2002, Israeli forces arrested the other chief planner, . On 22 September 2005, al-Sayed was convicted of the Passover attack and also of ordering the May 2001 bombing of a Netanya mall. He received 35 life sentences for each murder victim and additional time for those who were wounded. Fathi Khatib, who transported the bomber to his target, Mohand Sharim, who financed the operation and helped hide the bomber, Muammar Abu Sheikh, who recruited the bomber to Hamas and transferred the explosive belts used in the attack to an explosives expert for examination, and Nasser Yatiya, who helped transport the explosive belts, were tried and convicted together in an Israeli military court in April 2003 and handed 29 life sentences. Nasser Yatiya was released in the Gilad Shalit prisoner exchange in 2011. Muhammad Taher, who prepared the explosive charges, was killed in a clash with Israeli Shayetet 13 naval commandos in June 2003. On 26 March 2008 Hamas commander Omar Jabar, suspected of helping organize the attack, was arrested in Tulkarem
