Verified videos emerging from Iran show bodies piled up in a hospital, snipers stationed on buildings, and CCTV cameras being destroyed, following the unprecedented crackdown on protests earlier this month.

BBC Verify has been tracking the spread of protests across Iran since they first erupted in late December. However, the near-total internet blackout imposed by authorities has made it extremely difficult to document the scale of the state's deadly crackdown on protesters.

The US-based Human Rights Activists News Agency (HRANA) reports the killing of nearly 6,000 people, including 5,633 protesters, since the unrest began. They continue to investigate an additional 17,000 reported deaths received despite the ongoing challenges of reporting since the internet shutdown.

Another group, Norway-based Iran Human Rights (IHR), has warned that the final toll could exceed 25,000. Iranian authorities claim that over 3,100 people were killed, the majority being security personnel or bystanders attacked by rioters.

The latest videos are believed to have been filmed on January 8 and 9, during a surge of protests following a call from Reza Pahlavi, the exiled son of the late Shah. These nights have been described as some of the deadliest for protesters, with additional verified footage highlighting the violent actions of Iran's security forces.

Multiple clips analyzed show bodies within a mortuary at Tehranpars hospital and body bags outside its entrance, adding to the alarming toll. Protesters appear visible attempting to evade surveillance, disabling CCTV cameras as large crowds gather.

Reports from various cities indicate armed forces and snipers visibly positioned on rooftops. A video from the city of Mashhad captured armed personnel during daylight, raising concerns about public safety amid ongoing protests.

The internet blackout initiated on January 8 has hindered communication, yet some accounts have utilized satellite internet options to share updates from inside the country.

Given the situation, more footage may emerge as the nation grapples with growing tensions and severe human rights concerns.
