IDF) Palestinians were executed on suspicion of collaboration during the span of the Intifada. Other notable events On 16 April 1988, a leader of the PLO, Khalil al-Wazir, nom de guerre Abu Jihad or 'Father of the Struggle', was assassinated in Tunis by an Israeli commando squad. Israel claimed he was the 'remote-control "main organizer" of the revolt', and perhaps believed that his death would break the back of the intifada. During the mass demonstrations and mourning in Gaza that followed, two of the main mosques of Gaza were raided by the IDF and worshippers were beaten and tear-gassed. In total between 11 and 15 Palestinians were killed during the demonstrations and riots in Gaza and West Bank that followed al-Wazir's death. In June of that year, the Arab League agreed to support the intifada financially at the 1988 Arab League summit. The Arab League reaffirmed its financial support in the 1989 summit. Israeli defense minister Yitzhak Rabin's response was: "We will teach them there is a price for refusing the laws of Israel." When time in prison did not stop the activists, Israel crushed the boycott by imposing heavy fines and seizing and disposing of equipment, furnishings, and goods from local stores, factories and homes. On 8 October 1990, 22 Palestinians were killed by Israeli police during the Temple Mount riots. This led the Palestinians to adopt more lethal tactics, with three Israeli civilians and one IDF soldier stabbed in Jerusalem and Gaza two weeks later. Incidents of stabbing persisted. The Israeli state apparatus carried out contradictory and conflicting policies that were seen to have injured Israel's own interests, such as the closing of educational establishments (putting more youths onto the streets) and issuing the Shin Bet list of collaborators. Suicide bombings by Palestinian militants started on 16 April 1993 with the Mehola Junction bombing, carried at the end of the Intifada. United Nations The large number of Palestinian casualties provoked international condemnation. In subsequent resolutions, including 607 and 608, the Security Council demanded Israel cease deportations of Palestinians. In November 1988, Israel was condemned by a large majority of the UN General Assembly for its actions against the intifada. The resolution was repeated in the following years. Security Council On 17 February 1989, the UN Security Council drafted a resolution condemning Israel for disregarding Security Council resolutions, as well as for not complying with the fourth Geneva Convention.
