The Iranian judiciary has upheld the death sentence imposed on a man involved in the nationwide protests.
The death penalty for Mohammed B. was "confirmed by the Supreme Court" on December 6, the judiciary declared on its website "Misan Online" on Monday.
The death sentence against a second suspect was also confirmed in December.
The two men can no longer appeal and can be executed at any time.
B. was tried for being an "enemy of God" - a charge punishable by the death penalty.
According to Misan Online, he was accused of attacking a security officer with a knife and "terrifying the citizens".
He was also charged with “setting fire” to the administrative headquarters in the city of Pakdasht, south-east of the capital, Tehran.
According to its own statements, the Iranian judiciary has imposed a total of eleven death sentences in connection with the protests.
Activists assume a higher number.
Two death sentences have already been carried out.
In the case of three other convicts, including a Kurdish rapper, a new trial has been scheduled by order of the Supreme Court.
No decision has yet been made public on the appeal lodged by four other death row inmates.
Iran has been shaken by a wave of protests since the death of the young Iranian Kurd Mahsa Amini on September 16.
The 22-year-old died after being arrested by the vice squad for violating the Islamic Republic's strict dress code.
The Iranian authorities have denounced the nationwide demonstrations as "riots".
Hundreds of people were killed in the protests.
Thousands more people were arrested.
