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.”

Iranians took to the streets in new protests on Friday to press the biggest movement against the Islamic republic in more than three years, as authorities sustained an internet blackout as part of a crackdown that has left dozens dead.

Iran’s supreme leader vowed that authorities will not back down in the face of the rapidly growing protest movement, setting the stage for an intensified violent crackdown.
