I’ve worked as a surgeon in disaster zones. Nothing compares to the nightmare I saw in Iran’s hospitals when the state started shooting protesters

By 8 January, Iran’s anti-regime protests that began in late December had spread across the country with reports of at least 45 people killed by security forces. Over the next three days the regime appears to have instigated a brutal crackdown on protesters that is now estimated to have led to the deaths of more than 5,000 people.

By the time I reached the hospital in Tehran on Thursday (8 January) night, the sound of the city had already changed.
