Amnesty International says Iran has executed a Kurdish activist who was awaiting the outcome of a Supreme Court appeal.
The London-based group says Behrouz Alkhani, 30, was executed on August 26.
He was convicted in 2011 of having ties to the outlawed Party of Free Life of Kurdistan (PJAK) and of being involved in the shooting of a public prosecutor in 2010.
Alkhani's brother, Peyman, confirmed to Reuters news agency that he was a PJAK member but said he never took up arms.
Amnesty called Alkhani's trial "grossly unfair" and said his execution was a "denigration" of both Iranian and international law.
Earlier this month, Iran executed another PJAK member, Sirvan Nezhavi. The group’s military wing retaliated by attacking a Islamic Revolutionary Guards Corps base near the Iraqi border.
The Kurdish fighters said they killed 12 Iranian soldiers, while Iran only confirmed five deaths.
