At least 31 prisoners were hanged in various Iranian prisons in one week. Another prisoner on death row also committed suicide in Ghezel Hesar prison in Karaj this week, according to human rights reports.

Iran led the world in executions this year, with at least 800 documented cases as of December 1, according to the Death Penalty Information Center (DPI).

"Despite the overall global trend towards abolition, total known executions worldwide increased for the third consecutive year, led by Iran, Saudi Arabia, and Iraq," according to recent data from the DPI.
