Two prominent critics of Iran's government have been arrested, an Iranian opposition Web site reported Monday.
The Rah-e-Sabz site said former foreign minister Ebrahim Yazdi and human rights activist Emad Baghi were arrested early Monday.
Yazdi, who served as foreign minister after the 1979 Islamic revolution, is now leader of the banned but tolerated Freedom Movement of Iran.
The arrests come a day after at least five people were killed during anti-government protests. Sunday's unrest was one of the bloodiest confrontations between the government and pro-reform activists in months.
