According to the human rights group, Sharmahd had created a website to publish statements from the KAI, including claims of explosions inside Iran.
The little-known US-based group, also known as Tondar (Persian for Thunder), seeks to restore the monarchy overthrown in the 1979 Islamic Revolution.
However, Iranian authorities said he was Tondar’s leader and had “planned 23 terror attacks”, of which “five were successful”, including the 2008 bombing of a mosque in Shiraz in that killed 14 people.
They published a video in which he appeared blindfolded and confessed to various crimes.
When Sharmahd was sentenced in February last year, Germany’s Foreign Minister Annalena Baerbock condemned it as “absolutely unacceptable”.
