An unidentified man assassinated two influential judges before killing himself outside the Supreme Court in Tehran, the judiciary portal Mizan reported on Saturday.
The victims were the renowned clerics Ali Razini and Mohammed Moghiseh, who were responsible at the Islamic Revolutionary Court for convicting dissidents and alleged traitors.
Another judge and his bodyguard were seriously injured in the attack.
Security authorities are investigating the identity and motive of the assailant.
According to unconfirmed reports, the attacker is said to have been a member of the courthouse kitchen staff.
State media described the incident as a "terrorist act” against two judges.
Observers suggested the attack could have been politically motivated because the two clerics were responsible for numerous verdicts against dissidents.
