Iran protesters tell of brutal police response as regime lashes out

Videos emerging despite internet and mobile phone blackout show demonstrations continuing despite reports of escalating crackdown

Demonstrators have continued to take to the streets of Iran, defying an escalating crackdown by authorities against the growing protest movement.

An internet shutdown imposed by the authorities on Thursday has largely cut the protesters off from the rest of the world, but videos that trickled out of the country showed thousands of people demonstrating in Tehran overnight into Saturday morning. They chanted: Death to Khamenei," in reference to supreme leader Ayatollah Ali Khamenei, and: Long live the shah."
