The Sunday Times has reported, citing doctors, that at least 16,500 Iranian protesters have been killed by the Islamic Republic's suppressors, and over 330,000 other protesters have been injured. The report indicates that most of the fatalities occurred during two days of complete slaughter (Thursday, January 18, and Friday, January 19). The Sunday Times describes this massacre as "the most brutal crackdown by the clerical regime in its 47 years of existence."

This report, authored by Christina Lamb, references a confidential report attributed to doctors inside Iran. According to this report, due to a nationwide internet and communication blackout, the ability to document and independently verify events has been severely limited, and doctors have reported an increase in the scale of violence and casualties.

The report states that government forces have fired on protesters using military weapons and snipers, with many of the victims being young people under 30 years old. It also mentions instances of bodies being transferred from hospitals and secret burials.

The Sunday Times emphasizes that due to communication restrictions, independent verification of these figures is difficult, and other human rights sources have provided different numbers. This report comes amid ongoing concerns about the human rights situation and the crackdown on protesters in Iran. Additionally, the Sunday Times cites doctors inside Iran indicating that likely more than 8,000 protesters have been blinded across the country.
