Iran protests: Shots fired as security forces chase protesters

Video footage, verified by the BBC, shows the dramatic moment protesters run for cover in the Iranian city of Sanandaj, as security personnel on motorbikes drive towards them. Gunfire is heard as they duck into an alley.

Sanandaj has been the epicentre of the protests in Kurdistan province.

Several protesters have been shot dead by security forces there over the past month, according to Kurdish human rights activists.
