The head of Iran`s judiciary signalled on Wednesday that there would be fast trials and executions ahead for those detained in nationwide protests despite a warning from US President Donald Trump.

The comments from Iran`s judiciary chief Gholamhossein Mohseni-Ejei come as activists had warned hangings of those detained could come soon. Already, a bloody security force crackdown on the demonstrations has killed at least 2,571, the US-based Human Rights Activists News Agency reported. That figure dwarfs the death toll from any other round of protest or unrest in Iran in decades and recalls the chaos surrounding the country`s 1979 Islamic Revolution.
