ISLAMABAD: Pakistani students returning from Iran on Thursday said they heard gunshots and stories of rioting and violence while being confined to campus and not allowed out of their dormitories in the evening.

Iran’s leadership is trying to quell the worst domestic unrest since its 1979 revolution, with a rights group putting the death toll over 2,600.

As the protests swell, Tehran is seeking to deter US President Donald Trump’s repeated threats to intervene on behalf of anti-government protesters.

“During ‌nighttime, we would ‌sit inside and we would hear gunshots,” Shahanshah ‌Abbas, ⁠a fourth-year ‌student at Isfahan University of Medical Sciences, said at the Islamabad airport.

“The situation down there is that riots have been happening everywhere. People are dying. Force is being used.”
