A Twitter account dedicated to news about protests in Iran has released a batch of death certificates of those killed by security forces.

The activist account 1500 Tasvir, which runs popular Instagram and Twitter accounts, started uploading the documents on Wednesday.

The account also published a large batch of harrowing photos and videos of people shot or killed by the regime late in March, saying that such documentation must remain forever in the country’s history.

The cause of death for hundreds of people who died during the protests of "Women, Life, Liberty” movement is stated as "unknown", and the death certificates of dozens of others attested the use of "live fire and bullets" as the cause of death.

Other causes of death mentioned in the certificates are ruptures of veins or blood vessels, crushing of the skull, hemorrhagic shock (loss of a large volume of blood), and severe tissue damage, all of which point to injuries caused by the security forces’ bullets and batons.

In several cases, the words live fire or bullet are intentionally avoided and replaced by alternative terms such as "accelerated metal projectile" or “metal object."

There are several cases in which the cause of death is declared as “unknown” despite testimonies by eyewitnesses who were present at the scene and directly testified otherwise. These include the cases of Mehrshad Shahidinejad and Sina Malayeri, two protesters who were beaten to death by batons during rallies in the city of Arak according to eyewitnesses.

In one of the certificates published by 1500tasvir, the cause of the death of Behnam Layeghpour was declared as “violence by other protesters” despite his family's account of the incident. Layeghpour was reportedly shot two times in his throat and chest from close range in October as his fiancée was watching. A security agent stood over him and prevented people from helping him at gunpoint.

Human rights sources have reported the death of over 500 protesters, including about 70 children, during nationwide protests sparked by the death of 22-year-old Mahsa Amini in the custody of hijab police in September 2022.

There are no official reports about the number of casualties but several rights groups, such as the US-based Human Rights Activists News Agency (HRANA), have put the death toll at way more than 500.

In addition to the people who were killed during the regime’s crackdown on street protests, the Islamic Republic has also stepped up its executions in the past several months.

Iran Human Rights organization and the ECPM (Ensemble contre la peine de mort or Together Against the Death Penalty) released on Thursday their latest annual report on the death penalty in Iran, revealing that 2022 had the highest annual number of executions since 2015. At least 582 people were executed, an increase of 75 percent compared to 2021.

The report said that in 2022, the Islamic Republic’s authorities “demonstrated how crucial the death penalty is to instil societal fear in order to hold onto power,” adding that 88 percent of all executions (511), were not announced by the regime.

According to the report, at least 15 people, among them two protesters, were executed for security-related charges. It also claimed that hundreds of protesters were facing show trials at the Revolutionary Courts, many with charges punishable by death.
