Iranian opposition leader Mirhossein Mousavi's website reported Thursday security forces had attacked his office and seized his computers. The Kaleme website said some of his belongings were taken along with the computers.
Mousavi, who lost to hardline President Mahmoud Ahmadinejad in a disputed election in June 2009, has remained the main leader of the reformist "Green" movement.
Earlier this month, opposition websites reported that members of the Basij militia smashed windows and damaged security cameras at the home of another opposition leader Mehdi Karoubi, injuring one of his bodyguards.
