Iran has executed two men arrested during the period of widespread unrest that erupted after June's disputed presidential election, reports say.
They had been convicted of being "enemies of God", members of armed groups and trying to topple the Islamic establishment, Isna news agency said.
The executions are believed to be the first related to last year's protests.
Millions demanded a re-run of June's poll at the largest demonstrations in Iran since the 1979 Islamic Revolution.
Opposition groups said it had been rigged to ensure the re-election of President Mahmoud Ahmadinejad, a charge the government denied.
At least 30 protesters have been killed in clashes since the elections. Thousands were detained and some 200 activists remain behind bars.
Isna quoted a statement from the Tehran prosecutor's office naming the two men, who were reportedly hanged at dawn on Thursday, as Mohammad Reza Ali Zamani and Arash Rahmanipour.
There has been no independent confirmation of the executions or the names, but opposition groups had previously said Mr Zamani was sentenced to death in October.
He and one other person were believed to have been convicted for ties with the Kingdom Assembly of Iran, a banned monarchist group.
