BBC News Persian has verified the identities of more than 200 of the thousands of people killed during Iran's brutal crackdown on the recent widespread protests.
The project has scoured social media, verified online footage and used eyewitness accounts to build up a chronicle of how and when the protesters were killed, as well as some details about their lives.
Many of these accounts were provided to the BBC by sources close to the victims and were cross-checked against data from human rights organisations.
Since the unrest began in late December, the US-based Human Rights Activists News Agency (HRANA) has confirmed the deaths of 6,872 protesters, including more than 150 children.
Iranian authorities acknowledge that at least 3,000 people were killed, but claim some were members of the security forces.
The findings for this project were produced through multiple steps and interviews with sources inside Iran, many of whose names cannot be disclosed for safety reasons.
The BBC Visual Journalism team has created an interactive face wall for the BBC News Persian website, where readers can explore the profiles of victims identified through the research by clicking on each photograph.
The project is ongoing, and the team aims to add further names and stories as verification continues.
