LONDON: The United Nations Human Rights office has condemned Iran’s execution of a child offender as “appalling,” while questioning his access to fair judicial process throughout his trial. Mohammad Hassan Rezaiee was executed early Thursday morning in Iran for an offence he allegedly committed when he was 16 years old. Rezaiee, who spent 12 years behind bars before his execution was eventually carried out, is the fourth person Tehran has executed this year for crimes committed as a minor. The UN said 80 more child offenders remain on death row. UN High Commissioner for Human Rights Michelle Bachelet “strongly condemns the killing of Mohammad Hassan Rezaiee,” a statement from her office said.
