ISNA, citing a spokesman for a Tehran provincial court, did not identify those who received the death penalty, giving only their initials.

"The execution sentences were handed down because of involvement in post-election developments and affiliation with Iranian monarchical associations and the PMOI," the official said. "These sentences are not final and can be appealed in a higher court," he said.

The People's Mujahideen Organisation of Iran (PMOI) is an exiled opposition organisation, seen by both Iran and the United States as a terrorist group.
