Abdolfattah Soltani told RFE/RL's Radio Farda that his organization -- the Iranian Center to Defend Human Rights -- has been defending Iranian political and social activists "mistreated by Iran’s judiciary system" for about a decade.
Soltani is a lawyer and his NGO defends Iranians free of charge.
Prominent Iranian human rights activist and Nobel Peace Prize winner Shirin Ebadi is also a member of that NGO.
Together with her, Soltani represented the family of Iranian-Canadian journalist Zahra Kazemi, who died in suspicious circumstances in Iran's Evin prison in July 2003.
Soltani himself was imprisoned because of his activities in 2005.
