psychological damage and civilian casualties. In the 1990s, these groups seemed to threaten Arafat's capacity to hold together a unified nationalist organization with a goal of statehood. An attack carried out by Hamas militants in March 2002 killed 29 Israeli civilians celebrating Passover, including many senior citizens. In response, Israel launched Operation Defensive Shield, a major military offensive into major West Bank cities. Mahmoud al-Zahar, a Hamas leader in Gaza, stated in September 2010 that Arafat had instructed Hamas to launch what he termed "military operations" against Israel in 2000 when Arafat felt that negotiations with Israel would not succeed. Some Israeli government officials opined in 2002 that the armed Fatah sub-group al-Aqsa Martyrs' Brigades commenced attacks towards Israel in order to compete with Hamas. On 6 May 2002, the Israeli government released a report, based in part on documents, allegedly captured during the Israeli raid of Arafat's Ramallah headquarters, which allegedly included copies of papers signed by Arafat authorizing funding for al-Aqsa Martyrs Brigades' activities.

Arafat was finally allowed to leave his compound on 2 May 2002 after intense negotiations led to a settlement: six PFLP militants, including the organization's secretary-general Ahmad Sa'adat, wanted by Israel, who had been holed up with Arafat in his compound, would be transferred to international custody in Jericho. After the wanted men were handed over the siege was lifted. With that, and a promise that he would issue a call to the Palestinians to halt attacks on Israelis, Arafat was released. He issued such a call on 8 May. On 19 September 2002, the IDF largely demolished the compound with armored bulldozers in order to isolate Arafat. In March 2003, Arafat ceded his post as Prime Minister to Mahmoud Abbas amid pressures by the US. The Israeli security Cabinet on 11 September 2003 decided that "Israel will
