Scores of executions feared in Iran as 23-year-old hanged in public execution

Human rights group warns death of Majidreza Rahnavard a significant escalation of violence against protesters'

Fears are growing that Iran is preparing to execute scores more protesters after authorities hanged a 23-year-old man from a crane, in a public killing carried out less than a month after he was arrested and following a secretive trial.

Majidreza Rahnavard was sentenced to death by a court in the city of Mashhad, a centre of the protests, for allegedly killing two members of the paramilitary Basij force and wounding four others. The Basij, affiliated with the country's feared Revolutionary Guards, has been at the forefront of the state crackdown.
