The CPB also has a petition campaign for blogger Mojtaba Saminejad, who was recently given a 2-year prison sentence.  According to Reporters Without Borders:
He will appear in court again on 22 June to be tried on a charge of “insulting the prophets and the holy imams.” This extremely serious accusation could result in his being found guilty of apostasy, which carries the death penalty under article 512 of the Islamic criminal code.
