He was 85.
Today's report says Yazdi died in Izmir, Turkey, due to complications from cancer. He was a close ally of Ayatollah Ruhollah Khomeini, the late leader of the 1979 Islamic Revolution.
Yazdi's party, the Freedom Movement of Iran, was part of the revolution but later turned against the clerics as they consolidated power and crushed dissent. He was purged from office in early 1980s; he served as foreign minister in 1979 and a lawmaker until 1983.
