Iran may carry out the death sentence of Erfan Soltani today, a 26-year-old arrested last week in Karaj for alleged involvement in ongoing anti-government protests. Soltani was among thousands detained during the demonstrations. Within less than a week, he was tried, convicted, and sentenced to death, according to The Guardian.

Amnesty International expressed concern over Soltani’s case, warning that Iranian authorities might again be using rapid trials and executions to suppress dissent. The organization said officials informed Soltani’s family of his sentence on January 11. Due to widespread protests and internet shutdowns, Soltani has reportedly been unable to contact his loved ones.

Observers note that Iran is the world’s second-highest executor after China. The Norway-based Iran Human Rights organization reported that at least 1,500 people were executed in Iran last year, highlighting the country’s extensive use of capital punishment.
