Yazdi was Deputy Prime Minister for Revolutionary Affairs for the interim Iranian government in 1979 directly after the Islamic Revolution. He also served as Foreign Minister and was elected to the Islamic Consultative Assembly parliament, serving for 4 years.
As recently as Saturday, the day after Iranians went to the polls, Yazdi was speaking out against what he saw as a rigged election. Such discourse may have contributed to his arrest.
100 others have allegedly been detained alongside Yazdi.
