Mohammad Sabahi's mysterious death makes him the third Friday Imam of the relatively small town of around 100,000 people to have been killed since the 1979 Islamic revolution.
“Despite the efforts of the doctors and medical staff at Namazi Hospital in Shiraz, the Friday Imam has passed away due to the severity of his injuries,” Kazeroun’s governor, Mohammad Ali Bekhrad, told IRNA on Friday evening.
While refraining from using the word “martyred” - typically deployed when a person's death has a political or religious background - IRNA added that Sabahi was shot by an assailant after Friday prayers.
Imams are appointed to lead Friday prayers by official religious authorities ultimately led by Iran's supreme leader Ali Khamenei.
Conflicting reports initially emerged, with Iranian media first announcing Sabahi’s death and later describing his condition as critical following an armed attack in which the assailant committed suicide.
Bekhrad earlier denied the attack was an act of terrorism, instead suggesting that a personal conflict may have been behind the shooting.
While also refraining from using the word “martyred”, the governor told IRNA investigations into the details of the incident are ongoing.
