Later years and assassination
In January 1979, Oveissi was pressured to resign and leave the country. He settled in France just before the Iranian revolution on 11 February. In the immediate aftermath of the revolution, Ayatollah Sadegh Khalkhali, a religious judge and then chairman of the Revolutionary Court, informed the press that the death sentence was passed on the members of the Pahlavi family and former Shah officials, including Oveissi. Oveissi was shot dead, along with his brother, Gholam Hossein, on 7 February 1984 in Paris, Rue de Passy. Oveissi was at the age of 66. The Islamic Jihad claimed responsibility for the assassination. His death was considered by many as the blow that dealt the most setback to opposition groups poised to overthrow the revolutionary regime in Tehran. Two days before his assassination he was expected to fly back to the border of Iran to lead a counter revolutionary army of officers and men from elite divisions of the late Shah's military that was quartered in 22 makeshift barracks in eight Turkish villages and at five clandestine bases inside Iran. Since Oveissi had strong ties and the support of powerful members of the clergy including Grand Ayatollahs Shariatmadari and Abu al-Qasim al-Khoei his elimination was priority number one for the newly established revolutionary government.
