The Iranian Supreme Court has denied a retrial for Arvin Nathaniel Ghahremani, a Jewish Iranian man sentenced to death after killing a Muslim man named as Amir Shokri during a fight. Ghahremani, 20, claims he acted in self-defense.

The execution was previously scheduled for May 20, but it was postponed to consider another appeal. A new execution date has not yet been announced. The Oslo-based group Iran Human Rights (IHR) now says the Iranian Supreme Court rejected Ghahremani’s appeal.

The family of the deceased rejected an offer from Ghahremani’s representatives to pay compensation and pardon the killer. This procedure, provided for under Sharia law, allows the offender to avoid execution.
