The Islamic Resistance Movement (HAMAS), Palestinian Jihad (PIJ), Al Aqsa Martyrs' Brigade (AAMB), and Popular Front for the Liberation of Palestine (PFLP) (organizations), conducted suicide bombings targeting Israeli citizens and injuring more than 1,600 United States and foreign nationals (victims) (plaintiffs). The victims brought suit under the Alien Tort Statute (ATS), 28 U.S.C. § 1350 (2006), against Arab Bank (defendant), a bank operating within the Palestinian territories. The victims claimed the bank financed the bombings and other activities. The victims argued the bank was liable under the ATS for violations of the law of nations, including genocide, crimes against humanity, and the financing of attacks on civilians. The bank moved to dismiss the complaints, contending that the victims failed to state a claim because the alleged conduct, commonly referred to as "terrorism," did not constitute a violation of the law of nations because there was no international, widely agreed upon meaning of the term "terrorism."
