Iran’s two main opposition leaders, Mehdi Karroubi and Mir Hossein Mousavi, have been beaten up by security forces at a rally marking the anniversary of the Islamic revolution.
One of Mr Karroubi’s sons, Mohammad Taghi Karroubi, told BBC Persian TV that Iranian special forces, the police and some plain-clothes forces attacked his father and his supporters.
He said: “They used tear gas, batons and other weapons. They were armed and some were carrying cleavers and guns.
He also said : “They sprayed tear gas into my father’s face, burning him, and he was also hit on the head with a stone”. He added : My father’s face is burnt from the tear gas and his eye is injured”. BBC
