The BBC has been able to speak to several Iranians in recent days, as new footage emerges of the unprecedented crackdown on protests earlier this month. The internet blackout is now patchy, after weeks where a total shutdown made it difficult to understand what was happening in the country. The US-based Human Rights Activists News Agency (Hrana) says it has so far confirmed the killing of at least 6,159 people in Iran since the unrest began and is investigating another 17,000 reported deaths.
