Ayoub Karimi, an Iranian-Kurdish prisoner of conscience who has been held in Qezelhesar prison in Karaj for the past 14 years, was executed on November 29, according to human rights watchdogs.
The Norway-based group Iran Human Rights said Karimi's execution came along with the carrying out of the death sentences of six other prisoners, a sign of Tehran's continued increase in the meting out of capital punishment against political and religious dissenters.
"The execution of Ayoub Karimi, based on coerced confessions and without a fair trial, like the execution of other political prisoners, is a crime," said Mahmood Amiry-Moghaddam, director of Iran Human Rights.
"The authorities of the Islamic republic must be held accountable for this crime."
The identities of the six other prisoners executed along with Karimi were not disclosed, but the Hengaw rights group noted that Ghasem Abasteh, a co-defendant in Karimi's case, faced a similar fate last month. The remaining five defendants are still incarcerated and face the imminent threat of execution.
Karimi, Davoud Abdollahi, Farhad Salimi, Anwar Khezri, Khosrow Besharat, and Kamran Sheikheh were arrested in January 2010. They were subsequently sentenced by Tehran's Islamic Revolutionary Court on charges including "acting against national security" and "corruption on Earth."
Their death sentences were confirmed in 2020 amid allegations of coerced confessions and torture -- a claim supported by at least four prisoners in open letters.
Amnesty International said in a statement at the time that the trial was "grossly unfair," pointing to forced confessions under torture.
The rate of executions in Iran has been rising sharply, particularly in the wake of widespread protests that swept across the country last year following the death of 22-year-old Mahsa Amini in police custody for an alleged head-scarf violation.
Amnesty International says the regime in Tehran has executed more people than any other country in the world other than China so far this year.
United Nations Secretary-General Antonio Guterres said on November 2 that Iran was carrying out executions "at an alarming rate," while Iran Human Rights said more than 600 people had been executed in the country during the first seven months of the year.
