Thirteen Jews have been executed in Iran since the Islamic revolution, most of them were executed for their alleged connections to Israel. Among them, one of the most prominent Jews of Iran in the 1970s, Habib Elghanian who was the head of the Iranian Jewish community was executed by a firing squad by the Islamic government shortly after the Islamic Revolution of 1979 on the charge of having been in contact with Israel, among others. In May 1998, Jewish businessman Ruhollah Kadkhodah-Zadeh was hanged in prison without a public charge or legal proceeding, apparently for assisting Jews to emigrate.
