In a place called Malekshahi, in western Iran, protesters converge on a base run by the revolutionary guards.
They bang on the gates and throw stones at the walls and give voice to their collective rage.
In Iran, the economy is imploding, and people are struggling to survive.
The revolutionary guards respond with gunfire. Some protesters flee, others collapse on the spot, as bystanders attempt to carry the casualties away.
They will go on to call what happened ‘Bloody Saturday’.
Watch: What happened on ‘Bloody Saturday’?
The following day, 4 January, the protest reforms outside the main entrance of the regional hospital.
Relatives of people who had been shot and injured in multiple gatherings, call for the end of the regime.
The security forces move in, on foot and on motorcycles, and gather in front of the facility.
Staff and civilians try to stop them from entering but the authorities force their way through the front door.
Amnesty International says security personnel entered the hospital on multiple occasions, arresting injured protesters and members of their family.
The human rights group says they also took bodies away to prevent displays of mourning.
