Esmaeil Mohammadi, a 38-year-old father of five, was a Kurdish activist who supported the Kurdish Komala organisation and had been arrested in the western Iranian town of Boukan in 2002. Mohammadi was reported tortured while in prison.
The second political prisoner executed was Mohammad Panj-Bini who was a member of separate Kurdish group.
Several other Kurdish activists are awaiting execution in Iranian Kurdistan.
