Mizan alleged Rahnavard had stabbed two security force members to death Nov. 17 in Mashhad and wounded four others.
Footage aired on state TV showed a man chasing another around a street corner, then standing over him and stabbing him after he fell against a parked motorbike. Another showed the same man stabbing another immediately after. The assailant, which state TV alleged was Rahnavard, then fled.
The Mizan report identified the dead as “student” Basij, paramilitary volunteers under Iran’s Revolutionary Guard. The Basij (ba-SEEJ’) have deployed in major cities, attacking and detaining protesters, who in many cases have fought back.
A heavily edited state television report aired after Rahnavard’s execution showed clips of him in the courtroom. In the video, he says he came to hate the Basijis after seeing video clips on social media of the forces beating and killing protesters.
The Mizan report accused Rahnavard of trying to flee to a foreign country when he was arrested.
Mashhad, a Shiite holy city, is located some 740 kilometers (460 miles) east of the Iranian capital, Tehran. Activists say it has seen strikes, shops closed and demonstrations amid the unrest that began over the Sept. 16 death in custody of Mahsa Amini, a 22-year-old woman who had been detained by Iran’s morality police.
Mizan said Rahnavard was convicted in Mashhad’s Revolutionary Court. The tribunals have been internationally criticized for not allowing those on trial to pick their own lawyers or even see the evidence against them.
Rahnavard had been convicted on the charge of “moharebeh,” a Farsi word meaning “waging war against God.” That charge has been levied against others in the decades since the 1979 Islamic Revolution and carries the death penalty.
In the images of his execution, a banner bearing a Quranic verse: “Indeed the requital of those who wage war against Allah and His Apostle, and try to cause corruption on the earth, is that they shall be slain or crucified, or shall have their hands and feet cut off from opposite sides, or be banished from the land.”
Executions conducted in public with a crane have been rare in recent years, though Iran used the same manner of hanging to put down unrest following the disputed 2009 presidential election and the Green Movement protests that followed.
Typically, those condemned are alive as the crane lifts them off their feet, hanging by a rope and struggling to breathe before they asphyxiate or their neck breaks.
Activists have put pressure on companies providing cranes to Iran in the past, warning they can be used for executions.
