On May 2, 1981, a police sapper was moderately injured by an explosive charge that had been placed in a trash can near Cafe Alno. On August 15, 1984, a car bomb was discovered on Ben Yehuda Street and defused about 10 minutes before it was to have exploded. In the car were about 12 kilograms of explosives and three kilograms of iron nails. On September 4, 1997, three Hamas suicide bombers simultaneously blew themselves up on the pedestrian mall, killing five Israelis. The bombing was carried out by Palestinians from the village of Asira al-Shamaliya. Three 14-year-old girls were killed in the attack: Sivann Zarka, Yael Botvin and Smadar Elhanan. Elhanan was the daughter of peace activist Nurit Peled-Elhanan and the granddaughter of Israeli general and politician Mattityahu Peled. The family of Yael Botvin, a U.S. citizen, filed a lawsuit in the United States against the Islamic Republic of Iran. A default judgment of $251 million in compensatory and punitive damages was awarded to the relatives of Americans killed in the attack. There were few assets of the Iranian government in the United States following the judgment. The plaintiffs threatened to seize valuable Persian artifacts located in Chicago museums and sell them for proceeds, leading to the Chicago's Persian heritage crisis, as well as suing the account of the Bank Melli Iran in the Bank of New York, but having the United States Department of Justice speak as amicus curiae in support of Bank Melli, advising that the bank had no responsibility for turning the funds over, resulted in a ruling against the students. On December 2, 2013, five U.S. families who were victims of the Iran-backed suicide bombing were awarded $9 million in federal court. On December 1, 2001, two suicide bombers detonated themselves on Ben Yehuda Street, followed by a car bomb set to go off as paramedics arrived. The suicide bombers killed eleven victims aged 15 to 21, including a number of soldiers out of uniform, and 188 were injured. Hamas claimed responsibility, stating that it was in retaliation for the killing of senior Hamas militant Mahmud Abu Hanoud. A Hamas spokesman in Gaza stated that these bombings did not assuage its lust for vengeance and that it would carry out further bombings. Lawsuits were filed against Arab Bank, NatWest and Crédit Lyonnais alleging that they channelled money to Hamas.
