A rights monitoring group has revealed horrifying details of torture inflicted on detainees in the case of a Basij agent killed during antigovernment protests.

The Follow-up Committee of Iranian Detainees, an independent organization monitoring the status of protesters arrested during anti-regime rallies across the country, reported that the prisoners linked to the death of Basij member Rouhollah Ajamian were subjected to brutal methods. These methods included hanging them for extended periods while their hands and feet were cuffed behind their backs.

While earlier reports hinted at torture and forced confessions, this recent disclosure reveals the extent of the abuse. A source close to the accused in the case revealed that the torture had persisted for over a month. It involved methods such as mock executions, electric shocks, punches, kicks, and prolonged beatings.

Iran executed Mohammad-Mehdi Karami and Mohammad Hosseini in January, and this week the country's Supreme Court upheld harsh sentences for several other protesters allegedly involved in the killing of the Basij agent during antigovernment demonstrations near the capital Tehran in October.

Fourteen protestors faced trial in the case, with some receiving sentences of up to 15 years, which has been criticized by human rights advocates. "On the day the sentences were issued, everyone was sentenced to 25 years in prison, and five were sentenced to death," the committee cited an informed source as saying.

According to the rights group, Karami and Hosseini were told they had been pardoned just one day before their execution.
