Complaints were lodged against former Israeli Defense Forces chief of General Staff Lt.-Gen. (res.) Dan Halutz and six other senior Israeli political and military officials by pro-Palestinian organizations, who sought to prosecute them in Spain under the principle of universal jurisdiction. On 29 January 2009, Fernando Andreu, a judge of the Audiencia Nacional, opened preliminary investigations into claims that a targeted killing attack in Gaza in 2002 warranted the prosecution of Halutz, the former Israeli defence minister Binyamin Ben-Eliezer, the former defence chief-of-staff Moshe Ya'alon, and four others, for crimes against humanity. Israeli Prime Minister Benjamin Netanyahu strongly criticized the decision, and Israeli officials refused to provide information requested by the Spanish court. The attack killed the founder and leader of the military wing of the Islamic militant organisation Hamas, Salah Shehade, who Israel said was responsible for hundreds of civilian deaths. The attack also killed 14 others (including his wife and 9 children). It had targeted the building where Shahade hid in Gaza City. It also wounded some 150 Palestinians, according to the complaint (or 50, according to other reports). The Israeli chief of operations and prime minister apologized officially, saying they were unaware, due to faulty intelligence, that civilians were in the house. The investigation in the case was halted on 30 June 2009 by a decision of a panel of 18 judges of the Audiencia Nacional. The Spanish Court of Appeals rejected the lower court's decision, and on appeal in April 2010 the Supreme Court of Spain upheld the Court of Appeals decision against conducting an official inquiry into the IDF's targeted killing of Shehadeh.
