Distressing new videos have emerged from a mortuary in Tehran showing rows of bodies, blood soaked floors and crowds of people searching for loved ones following a deadly government crackdown on protesters in Iran.
The videos analysed by BBC Verify and BBC Persian, which are too graphic to show, contain some of the most shocking examples so far of how brutal the government's retaliation has been since the unrest began on 28 December.
Forensic examination of the footage reveals nearly 200 bodies laid throughout the mortuary complex, many with visible wounds and one victim identified as young as 16.
Anti-government demonstrations have spread to more than 68 towns and cities, verified videos show, though the true figure is likely to be much higher. The near total internet blackout imposed by the government since last week has left more than 90 million Iranians almost completely cut off from the outside world.
