TEHRAN (AFP) - Iran has sentenced Ebrahim Yazdi, the head of a banned opposition party and a former foreign minister, to eight years in prison for "attempting to act against national security," his lawyer said Wednesday. Mohammad Ali Dadkhah told AFP that his 80-year-old client was also accused of "cooperating with the Freedom Movement of Iran party," an outlawed but tolerated group. Yazdi was found guilty in the closed-door session reportedly held on November 2. Dadkhah said Yazdi was also handed a five-year ban on civic activities.
