On October 3 and December 28, 2001, the families of the 241 U.S. peacekeepers who were killed as well as several injured survivors filed civil suits against the Islamic Republic of Iran and the Ministry of Information and Security (MOIS) in the U.S. District Court for the District of Columbia.[139] In their separate complaints, the families and survivors sought a judgment that Iran was responsible for the attack and relief in the form of damages (compensatory and punitive) for wrongful death and common-law claims for battery, assault, and intentional infliction of emotional distress resulting from an act of state-sponsored terrorism.[139]
