When he was 15 years old, Khosroshahi joined the leader of militant
Fada'iyan-e Islam (Devotees of Islam),
Sayyid Mojtaba Mir-Lohi, nicknamed Navvab Safavi. He was close to
Egypt's Muslim Brotherhood and reportedly the first person to identify himself as
ikhwani (Islamist) Shia. In at least two interviews, he claims to have sought and been denied Khomeini's approval for the assassination of the Islamic Republic's first President,
Abolhassan Bani Sadr and Iran's last Queen
Farah Pahlavi, both living in exile in
Paris. Khosroshahi was a prominent figure in the
Qom Seminary and was a representative of
Ayatollah Khomeini in the
Ministry of Culture and Islamic Guidance after the victory of the
Iranian Revolution in 1979. After two years, he became the Ambassador of the Islamic Republic to the Vatican. He was the first Shi'a clergy serving and representing the
Islamic Republic at the Vatican. While in the Vatican, he founded the Europe's Islamic Culture Center, a base for propagating
Shi'ism in the West. After serving in the Vatican, Khosroshahi was sent to
Cairo, where he represented Tehran for two years at the Islamic Republic's Interest Section. ==Death==
