An Iranian semi-official news agency says the Islamic Republic's judiciary has taken unspecified legal action against two opposition leaders who have been under house arrest for three years.
Fars quoted senior judiciary official Mohammad Javad Larijani on Tuesday as saying he was hopeful that Mir Hossein Mousavi and Mahdi Karroubi could have their house arrest lifted after the conclusion of the case.
Hard-liners blame the two for unrest that followed the disputed 2009 re-election of former President Mahmoud Ahmadinejad. They were put under house arrest during 2011 Arab Spring uprisings, along with Mousavi's wife, but were not charged with any crime.
Ahmadinejad fell out of favor with the country's clerical establishment, and new President Hassan Rouhani is moderate-leaning. But hard-liners still strongly denounce those involved in the 2009 unrest.
