Ahmed Zaki Yamani (Arabic: أحمد زكي يماني‎; born 30 June 1930) is a Saudi Arabian politician who was Minister of Oil (Petroleum) and Mineral Resources from 1962 until 1986 for his country, and a minister in OPEC for 25 years. In December 1975, Yamani and several other OPEC ministers were taken hostage by notorious terrorist Carlos (the Jackal) in Vienna, Austria. He was later released after Carlos spent two days riding an airplane across the Middle East even though Carlos was ordered by his superiors to execute Yamani.
